原文:Android项目实战（二十七）：数据交互（信息编辑）填写总结
前言：
项目中必定用到的数据填写需求。比如修改用户名的文字编辑对话框，修改生日的日期选择对话框等等。现总结一下，方便以后使用。
注：
先写实现过程，想要学习的同学可以看看，不需要的同学可以直接拉到最下面复制代码使用。
------------------------------------------------------------------------------------------------------------------------------------
一、文字编辑对话框
看下效果图（仿今日头条）：
需求包括：
一个标题TextView
一个圆角白色背景EditText
一个可输入个数提示的TextView
两个按钮，‘确定’、‘取消’
对话框展现形式。
代码实现：
（1）编写布局文件
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/grey_5" android:id="@+id/popup_edit_info_ly" > <!--标题--> <TextView android:id="@+id/popup_edit_info_txt_title" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="title" android:gravity="center_horizontal" android:padding="@dimen/dp_6" android:textColor="@color/black" /> <!--编辑框--> <EditText android:id="@+id/popup_edit_info_edit_content" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="@dimen/dp_6" android:layout_marginRight="@dimen/dp_6" android:background="@drawable/bg_popup_edit" android:padding="@dimen/dp_6" > </EditText> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="@dimen/dp_6" > <!--提示文字--> <TextView android:id="@+id/popup_edit_info_txt_tip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="@dimen/txt_10" android:text="剩余可输入个数:" android:layout_centerVertical="true" android:layout_marginLeft="@dimen/dp_6" /> <!--确定按钮，这里用TextView ，当然也可以用Button ImageButton--> <TextView android:id="@+id/popup_edit_info_btn_confirm" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/confirm" android:background="@drawable/bg_btn_blue" android:padding="@dimen/dp_4" android:textColor="@color/white" android:layout_alignParentRight="true" /> <!--取消按钮--> <TextView android:id="@+id/popup_edit_info_btn_cancel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/cancel" android:background="@drawable/bg_btn_grey" android:padding="@dimen/dp_4" android:textColor="@color/white" android:layout_toLeftOf="@id/popup_edit_info_btn_confirm" android:layout_marginRight="@dimen/dp_10" /> </RelativeLayout></LinearLayout>
dialog_edit_txt
里面编辑框EditView涉及到了圆角白色背景 需要写一个drawable文件
<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"> <!--popupwindow 编辑框的背景颜色 用于popup_edit_info.xml布局文件--> <solid android:color="@color/white" ></solid> <corners android:radius="@dimen/dp_6"></corners> <stroke android:width="0.5dp" android:color="@color/grey_1"></stroke></shape>
bg_popup_edit
(2)、在activity或者fragment中使用
①、这里我把对话框写在一个方法里，方便使用
title 文本对话框的标题
isSingleLine EditText是否限制一行显示
maxSize EditText中文字的最大长度
textview 修改的TextView控件，首先要讲该控件的文本显示在EditText中，点击确定后需要将编辑文本显示在改控件中
private void showEditDialog(String title , boolean isSingleLine , final int maxSize, final TextView textview)
②、根据布局文件生成view 并 初始化控件
View view = LayoutInflater.from(this).inflate(R.layout.dialog_edit_txt, null); TextView popup_edit_info_txt_title;//标题 final TextView popup_edit_info_txt_tip; //编辑框剩余个数提示 TextView popup_edit_info_btn_cancel; //取消按钮 TextView popup_edit_info_btn_confirm; //确定按钮 final EditText popup_edit_info_edit_content; //编辑框 popup_edit_info_txt_title = (TextView) view.findViewById(R.id.popup_edit_info_txt_title); popup_edit_info_txt_tip = (TextView) view.findViewById(R.id.popup_edit_info_txt_tip); popup_edit_info_btn_cancel = (TextView) view.findViewById(R.id.popup_edit_info_btn_cancel); popup_edit_info_btn_confirm = (TextView) view.findViewById(R.id.popup_edit_info_btn_confirm); popup_edit_info_edit_content = (EditText) view.findViewById(R.id.popup_edit_info_edit_content);
③、进行控件的属性设置
popup_edit_info_edit_content.setText(textview.getText().toString()); // 将参数textview的文本数据显示在EditText中 popup_edit_info_edit_content.setSingleLine(isSingleLine); // 设置EditView是否单行，像用户名这种信息需要单行，像评价简介这种的不需要单行 popup_edit_info_edit_content.setFilters(new InputFilter[]{new InputFilter.LengthFilter(maxSize)}); // 设置EditText的最大长度，当输入超过这个值的时候不在允许输入 popup_edit_info_txt_tip.setText("剩余可输入个数:"+(maxSize-textview.getText().toString().length())); // 设置 剩余文字个数提示
popup_edit_info_edit_content.setSelection(content.getText().length()); // 光标默认显示在最后
final AlertDialog dialog = new AlertDialog.Builder(this) //创建对话框 .setView(view) .create(); popup_edit_info_txt_title.setText(title); // 设置标题
dialog.setCanceledOnTouchOutside(false); // 设置点击屏幕Dialog不消失
④、进行EditText的设置 ，监听文字数据字数变化，改变提示文本的内容
popup_edit_info_edit_content.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { } @Override public void afterTextChanged(Editable s) { int length = s.length(); popup_edit_info_txt_tip.setText("剩余可输入个数:"+(maxSize-length)); } });
⑤、设置‘确定’、‘取消’点击事件
popup_edit_info_btn_cancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); } }); popup_edit_info_btn_confirm.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { textview.setText(popup_edit_info_edit_content.getText().toString()); dialog.dismiss(); } });
⑥、显示对话框
dialog.show();
------------------------------------------------------------------------------------------------------------------------------------
二、单个条件选择的自定义PopupWindow
效果图：
需求包括：
1、顶部两个按钮：“取消”、“确定”按钮
2、标题
3、滚动的wheelview选择器
代码实现：
1、选择一个WheelView控件，这个github上很多，我这里选用的是
https://github.com/xiangyunwan/WheelView-master/
在app目录下的 build.gradle文件中添加
compile ‘com.wx.wheelview:wheelview:1.3.3‘
2、构建PopupWindow布局文件
这个比较简单，按效果图来 两个按钮，一个标题文本，一个WheelView
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/popup_one_item_ly" android:background="@color/white" > <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/grey_6" > <Button android:id="@+id/popup_one_item_btn_cancel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#0000" android:text="取消" android:textColor="@color/line_blue_main" /> <Button android:id="@+id/popup_one_item_btn_submit" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="确定" android:layout_alignParentRight="true" android:background="#0000" android:textColor="@color/line_blue_main" ></Button> <TextView android:id="@+id/popup_one_item_txt_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="@color/black" android:layout_centerInParent="true" /> </RelativeLayout> <com.wx.wheelview.widget.WheelView android:id="@+id/popup_one_item_wheel" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginLeft="@dimen/dp_20" android:layout_marginRight="@dimen/dp_20" > </com.wx.wheelview.widget.WheelView></LinearLayout>
popup_one_item
对应的几个资源：
<color name="grey_6">#faf9f9</color><color name="blue_main">#4ab8e9</color>
3、写一个封装的继承PopupWindow的类，以后类似的直接拿来用即可，这里命名OneItemPopupWindow
①、参数分析
需要上下文 Context 用于构建View
需要点击事件，接口回调的方式 View.OnClickListener
需要标题文本，String
需要WheelView显示的数据源，ArrayList<String>
所以构造方法：
public OneItemPopupWindow(Context context, View.OnClickListener itemsOnClick, String t, ArrayList<String> datas) { super(context);}
②、定义需要的数据
private View mMenuView; //popupwindow布局生成的View private TextView title; //标题 private Button cancel; //取消按钮 private Button submit; //确定按钮 private WheelView wheel; //wheelview控件 private int currentPosition; // 当然的wheelview选择的item的位置 ArrayList<String> datas = new ArrayList<>(); // wheelview的数据源
③、生成PopupWindow的View 并获取相应控件 初始化， 从这里开始都写在构造方法里
LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); mMenuView = inflater.inflate(R.layout.popup_one_item, null); cancel = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_cancel); submit = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_submit); wheel = (WheelView) mMenuView.findViewById(R.id.popup_one_item_wheel); title = (TextView) mMenuView.findViewById(R.id.popup_one_item_txt_title); this.datas = datas; //根据参数初始化数据源 title.setText(t); //设置标题
④、设置wheelview控件的相应属性方法
wheel.setWheelAdapter(new ArrayWheelAdapter(context)); // 文本数据源 wheel.setSkin(WheelView.Skin.Holo); // common皮肤 wheel.setWheelData(datas); // 数据集合 wheel.setOnWheelItemSelectedListener(new WheelView.OnWheelItemSelectedListener() { @Override public void onItemSelected(int position, Object o) { currentPosition = wheel.getCurrentPosition(); } }); cancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dismiss(); } }); submit.setOnClickListener(itemsOnClick);
⑤、设置PopupWindow的自身属性方法
this.setContentView(mMenuView); this.setWidth(ViewGroup.LayoutParams.MATCH_PARENT); this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); ColorDrawable dw = new ColorDrawable(0x000000); this.setBackgroundDrawable(dw); this.setFocusable(true); //点击popupWindow之外的部分 关闭popupWindow mMenuView.setOnTouchListener(new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { int height = mMenuView.findViewById(R.id.popup_one_item_ly).getTop(); int y = (int) event.getY(); if (event.getAction() == MotionEvent.ACTION_UP){ if(y<height){ dismiss(); } } return true; } });
到这里构造方法完成了，然后我们需要写一个方法，让new OneItemPopupWindow(...)的Activity能获取到数据源选中位置的数据
public int getCurrentPosition() { // 获取到wheelview当前选中的位置 return currentPosition; } public ArrayList<String> getDatas() { //获取wheelview的数据源 return datas; }
自定义 OneItemPopupWindow 的全部代码
import android.content.Context;import android.graphics.drawable.ColorDrawable;import android.view.LayoutInflater;import android.view.MotionEvent;import android.view.View;import android.view.ViewGroup;import android.widget.Button;import android.widget.PopupWindow;import android.widget.TextView;import com.maiji.magkarepatient.R;import com.wx.wheelview.adapter.ArrayWheelAdapter;import com.wx.wheelview.widget.WheelView;import java.util.ArrayList;/** * Created by 徐启鑫 on 2016/11/15. * 一个选项的popupwindow */public class OneItemPopupWindow extends PopupWindow{ private View mMenuView; //popupwindow布局生成的View private TextView title; //标题 private Button cancel; //取消按钮 private Button submit; //确定按钮 private WheelView wheel; //wheelview控件 private int currentPosition; // 当然的wheelview选择的item的位置 ArrayList<String> datas = new ArrayList<>(); // wheelview的数据源 public int getCurrentPosition() { return currentPosition; } public ArrayList<String> getDatas() { return datas; } public OneItemPopupWindow(Context context, View.OnClickListener itemsOnClick, String t, ArrayList<String> datas) { super(context); LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); mMenuView = inflater.inflate(R.layout.popup_one_item, null); cancel = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_cancel); submit = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_submit); wheel = (WheelView) mMenuView.findViewById(R.id.popup_one_item_wheel); title = (TextView) mMenuView.findViewById(R.id.popup_one_item_txt_title); this.datas = datas; //根据参数初始化数据源 title.setText(t); //设置标题 wheel.setWheelAdapter(new ArrayWheelAdapter(context)); // 文本数据源 wheel.setSkin(WheelView.Skin.Holo); // common皮肤 wheel.setWheelData(datas); // 数据集合 wheel.setOnWheelItemSelectedListener(new WheelView.OnWheelItemSelectedListener() { @Override public void onItemSelected(int position, Object o) { currentPosition = wheel.getCurrentPosition(); } }); cancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dismiss(); } }); submit.setOnClickListener(itemsOnClick); this.setContentView(mMenuView); this.setWidth(ViewGroup.LayoutParams.MATCH_PARENT); this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); ColorDrawable dw = new ColorDrawable(0x000000); this.setBackgroundDrawable(dw); this.setFocusable(true); //点击popupWindow之外的部分 关闭popupWindow mMenuView.setOnTouchListener(new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { int height = mMenuView.findViewById(R.id.popup_one_item_ly).getTop(); int y = (int) event.getY(); if (event.getAction() == MotionEvent.ACTION_UP){ if(y<height){ dismiss(); } } return true; } }); }}
OneItemPopupWindow
至此 封装好了一个 有一个筛选条件的 自定义PopupWindow
4、OneItemPopupWindow 的使用
ArrayList<String> condition = new ArrayList<>(); //构建数据源 condition.add("北京"); condition.add("上海"); condition.add("浙江"); condition.add("江苏"); condition.add("山东"); condition.add("山西"); condition.add("广东"); condition.add("福建"); popup = new OneItemPopupWindow(this, selectItemsOnClick,"选择城市",condition); //创建自定义的popupwindow对象 // 设置popupWindow显示的位置 // 此时设在界面底部并且水平居中 popup.showAtLocation(find_expert_ly, Gravity.BOTTOM| Gravity.CENTER_HORIZONTAL, 0, 0); // 当popupWindow 出现的时候 屏幕的透明度 ，设为0.5 即半透明 灰色效果 backgroundAlpha(0.5f); // 设置popupWindow取消的点击事件，即popupWindow消失后，屏幕的透明度，全透明，就回复原状态 popup.setOnDismissListener(new PopupWindow.OnDismissListener() { @Override public void onDismiss() { backgroundAlpha(1f); } });
5、监听事件的接口回调，也是写在创建 OneItemPopupWindow 对象的Activity中
private View.OnClickListener selectItemsOnClick = new View.OnClickListener() { public void onClick(View v) { switch (v.getId()) { //根据popupWindow 布局文件中的id 来执行相应的点击事件 case R.id.popup_one_item_btn_submit: String s = popup.getDatas().get(popup.getCurrentPosition()); find_expert_btn_location.setText(s); break; // .... } //每次点击popupWindow中的任意按钮，记得关闭此popupWindow， popup.dismiss(); } };
6、界面半透明效果方法
/** * 设置添加屏幕的背景透明度 * @param bgAlpha */ public void backgroundAlpha(float bgAlpha) { WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.alpha = bgAlpha; //0.0-1.0 getWindow().setAttributes(lp); }
效果图：
------------------------------------------------------------------------------------------------------------------------------------
三、日期选择的自定义DatePopupWindow
需求同上，一个标题，一个确定按钮 ，一个时间按钮
三个水平排列的wheelview选择空间
效果图:
代码实现：
1、 和 “单个条件选择的自定义PopupWindow” 实现类似，只是多了两个wheelview ，代码直接贴在最下面了

DatePopupWindow
3、使用代码：
private void showDatePopupWindow() { popup = new DatePopupWindow(this, selectItemsOnClick,"选择日期",2015); //创建自定义的popupwindow对象 // 设置popupWindow显示的位置 // 此时设在界面底部并且水平居中 popup.showAtLocation(feedback_list_ly, Gravity.BOTTOM| Gravity.CENTER_HORIZONTAL, 0, 0); // 当popupWindow 出现的时候 屏幕的透明度 ，设为0.5 即半透明 灰色效果 backgroundAlpha(0.5f); // 设置popupWindow取消的点击事件，即popupWindow消失后，屏幕的透明度，全透明，就回复原状态 popup.setOnDismissListener(new PopupWindow.OnDismissListener() { @Override public void onDismiss() { backgroundAlpha(1f); } }); } /** * 设置添加屏幕的背景透明度 * @param bgAlpha */ public void backgroundAlpha(float bgAlpha) { WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.alpha = bgAlpha; //0.0-1.0 getWindow().setAttributes(lp); } private View.OnClickListener selectItemsOnClick = new View.OnClickListener() { public void onClick(View v) { switch (v.getId()) { //根据popupWindow 布局文件中的id 来执行相应的点击事件 case R.id.popup_data_submit: feedback_list_plan_data.setText(popup.getCurrentYear()+"-"+popup.getCurrentMonth()+"-"+popup.getCurrentDay()); break; // .... } //每次点击popupWindow中的任意按钮，记得关闭此popupWindow， popup.dismiss(); } };
