android中“下次不再提示”的对话框（修改自某大神）

如图，我们要做得就是这个：

先上代码：

1，逻辑代码

 package com.example.hello;

 import android.app.Activity;
 import android.app.AlertDialog;
 import android.app.Dialog;
 import android.content.DialogInterface;
 import android.content.SharedPreferences;
 import android.content.SharedPreferences.Editor;
 import android.os.Bundle;
 import android.preference.PreferenceManager;
 import android.view.KeyEvent;
 import android.view.LayoutInflater;
 import android.view.View;
 import android.view.View.OnClickListener;
 import android.view.ViewGroup;
 import android.widget.Button;
 import android.widget.CheckBox;
 import android.widget.TextView;

 public class mima extends Activity {
     private static final String KEY_IS_SHOW_PWD_TIP = "KISPT";
     private static SharedPreferences sharedPreferences;
     private View newView;
     private TextView tv;

     private CheckBox cb;

     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

         // 用于填充AlertDialog的布局<<
         LayoutInflater inflater = LayoutInflater.from(this);
         newView = inflater.inflate(R.layout.dialog_item_add_quesgood, null);
         tv = (TextView) newView.findViewById(R.id.tv_add_quesGood);
         // >>

         cb = (CheckBox) newView.findViewById(R.id.cb_isShow);
         // 一定要做判断
         if (isShowPwdTip()) {
             showDialog(0);
         }
         Button bt =  (Button) findViewById(R.id.bt);
         bt.setOnClickListener(new OnClickListener() {

             @Override
             public void onClick(View v) {
                 // TODO Auto-generated method stub
                 if (isShowPwdTip()) {
                     showDialog(0);
                 }
             }
         });
     }

     @Override
     protected Dialog onCreateDialog(int id) {
         switch (id) {
         case 0: {
             //第二次点击弹出时将父view中存在的上一个子view删除（否则会出现java.lang.IllegalStateException:
             //The specified child already has a parent. You must call removeView() on the child's parent first.）
             ViewGroup vp = (ViewGroup) newView.getParent();
             if(vp != null){
                 vp.removeAllViews();
             }

             return new AlertDialog.Builder(mima.this)
                     .setView(newView)//自定义布局
                     .setOnKeyListener(new DialogInterface.OnKeyListener() {

                         @Override
                         public boolean onKey(DialogInterface dialog,
                                 int keyCode, KeyEvent event) {
                             if (event.getKeyCode() == KeyEvent.KEYCODE_SEARCH) {
                                 return true;
                             }
                             return false;
                         }
                     })
                     .setTitle("实验：")

                     .setPositiveButton("确定",
                             new DialogInterface.OnClickListener() {
                                 @Override
                                 public void onClick(DialogInterface dialog,
                                         int which) {
                                     if (cb.isChecked()) {
                                         removeDialog(0);
                                         closeShowPwdTip();
                                     } else {
                                         removeDialog(0);
                                     }
                                 }
                             })
                     .setNeutralButton("取消",
                             new DialogInterface.OnClickListener() {
                                 @Override
                                 public void onClick(DialogInterface dialog,
                                         int which) {
                                     removeDialog(0);
                                 }
                             }).create();
         }
         default: {
             return null;
         }
         }
     }

     public boolean closeShowPwdTip() {
         if (sharedPreferences == null)
             sharedPreferences = PreferenceManager
                     .getDefaultSharedPreferences(this);
         Editor editor = sharedPreferences.edit();
         editor.putBoolean(KEY_IS_SHOW_PWD_TIP, false);
         return editor.commit();
     }

     public boolean isShowPwdTip() {
         if (sharedPreferences == null)
             sharedPreferences = PreferenceManager
                     .getDefaultSharedPreferences(this);
         return sharedPreferences.getBoolean(KEY_IS_SHOW_PWD_TIP, true);
     }
 }

2，daialog布局布局

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:orientation="vertical" >

     <TextView
         android:id="@+id/tv_add_quesGood"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="您好，点击不再提示将不会再次出现此对话框，是否继续？"
         android:layout_marginTop="10dp"
         android:layout_marginLeft="10dp"
         />

     <CheckBox
         android:id="@+id/cb_isShow"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_marginLeft="4dp"
         android:text="不在提示"
         />
 </LinearLayout>

3，主界面布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="horizontal"
    tools:context=".MainActivity" >

<Button
    android:id="@+id/bt"
    android:text="点击"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />

</LinearLayout>

逻辑代码部分是我参考某大神修改的，因为忘了出处，还请见谅。

整个过程主要就是通过sharedPreferences 存储点击状态，再给Dialog自定义一个布局来完成的，代码可直接用。因为比较简单，就不浪费大家时间了。
