下面的代码将创建一个简单的警告对话框一个按钮。在下面的代码中使用setTitle()方法来设置Title to alert对话框。 setMessage()用于设置消息到警报对话框。 setIcon()是设置图标提醒对话框

AlertDialog alertDialog = new AlertDialog.Builder(
        AlertDialogActivity.this).create(); 

    // Setting Dialog Title 
    alertDialog.setTitle("Alert Dialog"); 

    // Setting Dialog Message 
    alertDialog.setMessage("Welcome to AndroidHive.info"); 

    // Setting Icon to Dialog 
    alertDialog.setIcon(R.drawable.tick); 

    // Setting OK Button 
    alertDialog.setButton("OK", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int which) { 
      // Write your code here to execute after dialog closed 
      Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show(); 
      } 
    }); 

    // Showing Alert Message 
    alertDialog.show();

protected final Dialog onCreateDialog(final int id) { 
    Dialog dialog = null; 
    switch (id) { 
    case DIALOG_ID: 
     AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setMessage(
       "some message") 
       .setCancelable(false) 
       .setPositiveButton("ok", 
         new DialogInterface.OnClickListener() { 
          public void onClick(DialogInterface dialog, 
            int id) { 
           //to perform on ok 


          } 
         }) 
       .setNegativeButton("cancel", 
         new DialogInterface.OnClickListener() { 
          public void onClick(DialogInterface dialog, 
            int id) { 

           //dialog.cancel(); 
          } 
         }); 
     AlertDialog alert = builder.create(); 
     dialog = alert; 
     break; 

    default: 

    } 
    return dialog; 
} 

你可以从任何地方像称之为：搜索

 showDialog(DIALOG_ID);
