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。
