如何在android studio中創建自動彈出窗口

Question

我想在應用程序的第一頁創建一個自動彈出窗口。但我似乎無法在網上找到任何教程。任何人請引導。任何幫助將升值。

感謝。

Answer 1

public void openDialog(View view){ 
    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this); 
    alertDialogBuilder.setMessage("Are you sure,You wanted to make decision"); 

    alertDialogBuilder.setPositiveButton("yes", new DialogInterface.OnClickListener() { 
    @Override 
    public void onClick(DialogInterface arg0, int arg1) { 
     Toast.makeText(MainActivity.this,"You clicked yes button",Toast.LENGTH_LONG).show(); 
    } 
    }); 

    alertDialogBuilder.setNegativeButton("No",new DialogInterface.OnClickListener() { 
    @Override 
    public void onClick(DialogInterface dialog, int which) { 
     finish(); 
    } 
    }); 

    AlertDialog alertDialog = alertDialogBuilder.create(); 
    alertDialog.show(); 

}

只需調用此方法openDialog（）;在你的setContentView（R.layout.activity_main）之後; 示例

setContentView(R.layout.activity_main); 
openDialog();
