Android對話框教程

1.1簡單提示框

1. //簡單提示框   
2.     private Dialog Dialog1(){  
3.         return new AlertDialog.Builder(XXXActivity.this).setTitle("提示").setMessage("提示內容太短").show();  
4.     }  

1.2多個按鈕提示框

1. @Override  
2.    protected Dialog onCreateDialog(int id) {  
3.     if(id == 1){//兩個按鈕提示框   
4.         return new AlertDialog.Builder(XXXActivity.this)  
5.                         .setTitle("提示").setMessage("提示內容太短")  
6.                         .setPositiveButton("確定", new DialogInterface.OnClickListener() {  
7.                               
8.                             @Override  
9.                             public void onClick(DialogInterface dialog, int which) {  
10.                                 // TODO Auto-generated method stub   
11.                                 dismissDialog(1);  
12.                             }  
13.                         })  
14.                         .setNegativeButton("取消", new DialogInterface.OnClickListener() {  
15.                               
16.                             @Override  
17.                             public void onClick(DialogInterface dialog, int which) {  
18.                                 // TODO Auto-generated method stub   
19.                                 dismissDialog(1);  
20.                             }  
21.                         }).create();  
22.     }else if(id == 2){//三個按鈕提示框   
23.         return new AlertDialog.Builder(XXXActivity.this)  
24.                     .setTitle("提示").setMessage("哈哈哈哈")  
25.                     .setIcon(R.drawable.ic_launcher)  
26.                     .setPositiveButton("注冊", new DialogInterface.OnClickListener() {  
27.                           
28.                         @Override  
29.                         public void onClick(DialogInterface dialog, int which) {  
30.                             // TODO Auto-generated method stub   
31.                               
32.                         }  
33.                     })  
34.                     .setNeutralButton("找回密碼", new DialogInterface.OnClickListener() {  
35.                         //注意這裡和下面的取消是不一樣的setNeutral.....setNegative   
36.                         @Override  
37.                         public void onClick(DialogInterface dialog, int which) {  
38.                             // TODO Auto-generated method stub   
39.                               
40.                         }  
41.                     })  
42.                     .setNegativeButton("取消", new DialogInterface.OnClickListener() {  
43.                           
44.                         @Override  
45.                         public void onClick(DialogInterface dialog, int which) {  
46.                             // TODO Auto-generated method stub   
47.                               
48.                         }  
49.                     }).create();  
50.     }else if(id ==4){ //圓形進度框   
51.         ProgressDialog dialog =  new ProgressDialog(XXXActivity.this);  
52.         dialog.setTitle("正在下載歌曲...");  
53.         dialog.setMessage("請稍候......");  
54.         return dialog;  
55.     }  
56.       
57.     return super.onCreateDialog(id);  
58.    }  

1.3自定義對話框

命名xxxx.xml文件是我們想要自定義的風格

1. <?xml version="1.0" encoding="utf-8"?>  
2. <LinearLayout xmlns:Android="http://schemas.android.com/apk/res/android"  
3.     android:layout_width="fill_parent"  
4.     android:layout_height="wrap_content"  
5.     android:orientation="vertical" >  
6.     <TextView android:layout_width="wrap_content" android:layout_height="wrap_content"  
7.          android:layout_marginLeft="20dip" android:layout_marginRight="20dip"  
8.          android:text="請輸入..." android:gravity="left"  
9.          android:textAppearance="?android:attr/textAppearanceMedium"/>  
10.     <EditText android:id="@+id/testdaysnum"  
11.         android:layout_height="wrap_content"   
12.         android:layout_width="fill_parent"  
13.         android:layout_marginLeft="20dip"  
14.         android:layout_marginRight="20dip"  
15.         android:scrollHorizontally="true"  
16.         android:autoText="false"  
17.         android:capitalize="none"  
18.         android:gravity="fill_horizontal"  
19.         android:textAppearance="?android:attr/textAppearanceMedium"  
20.         />  
21.       
22. </LinearLayout>  

1. //自定義Dialog   
2.        LayoutInflater factory = LayoutInflater.from(XXXActivity.this);  
3.        final View testDialogView = factory.inflate(R.layout.xxxx, null);  
4.        EditText edit_GetDayNum = (EditText)testDialogView.findViewById(R.id.testdaysnum);  
5.        new AlertDialog.Builder(XXXActivity.this)  
6.        .setTitle("提示")  
7.        .setView(testDialogView)  
8.        .setPositiveButton("確定", new DialogInterface.OnClickListener() {  
9.           
10.         @Override  
11.         public void onClick(DialogInterface dialog, int which) {  
12.             // TODO Auto-generated method stub   
13.               
14.             Toast.makeText(XXXActivity.this, "請等待...", Toast.LENGTH_LONG).show();  
15.         }  
16.     }).create().show();  

1. ProgressDialog m_Dialog = ProgressDialog.show(XXXActivity.this, "請等待...", "請稍候....",true);  

1.5Toast

1. Toast.makeText(XXXActivity.this, "請等待...", Toast.LENGTH_LONG).show();  

1. Dialog dialog = new Dialog(XXXActivity.this);  
2.         Window window = dialog.getWindow();  
3.         window.setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,  
4.         WindowManager.LayoutParams.FLAG_BLUR_BEHIND);  
5.         dialog.show();
