如何實現Android對話框？

Question

如何在我的android項目中實現對話框？

Answer 1

使用此代碼在任何你想顯示對話框..

AlertDialog.Builder builder =new AlertDialog.Builder(Dialogs.this); 
builder.setIcon(R.drawable.save1); 
builder.setTitle("Save Your Work"); 
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { 

@Override 
public void onClick(DialogInterface dialog, int which) { 
       // do something....... 
    } 
}); 
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 

@Override 
public void onClick(DialogInterface dialog, int which) { 
       // do something....... 
    } 
}); 
AlertDialog alert = builder.create(); 
alert.show();

您是在尋找簡單的AlertDialog或對話框？

例AlertDialog：

  AlertDialog.Builder alertDialog = new AlertDialog.Builder(Borc.this); 
       // Setting Dialog Title 
       alertDialog.setTitle("Eraser"); 
       // Setting Dialog Message 
       alertDialog.setMessage("Are you sure?"); 
       // Setting Icon to Dialog 
       alertDialog.setIcon(R.drawable.remove); 
       // Setting Positive "Yes" Button 
       alertDialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int which) { 
         dataBase.borclar.delete(String.valueOf(tableHelper.getSelectedRowId())); 
        } 
       }); 
       // Setting Negative "NO" Button 
       alertDialog.setNegativeButton("No", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int which) { 
        } 
       }); 
       // Showing Alert Message 
       alertDialog.show();

我想開始與Android對話的最好方式是閱讀文檔：Android Dialog Documentation。它們描述了各種類型的對話框以及如何在應用程序中實現它們。

如果您遇到特定問題，請告訴我們您的代碼並提出正確的問題。
