如何从AlertDialog中显示吐司？

Question

    AlertDialog.Builder alert = new AlertDialog.Builder(this);

    alert.setTitle(R.string.save_game);
    alert.setMessage(R.string.request_name);

    // Set an EditText view to get user input 
    final EditText input = new EditText(this);
    input.setHint(R.string.untitled);
    alert.setView(input);

    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
      String value = input.getText().toString();
      if(value != null){
          // Do something with value      
      }
      else{
          Toast.makeText(context, R.string.no_name_given, Toast.LENGTH_SHORT).show();
      }
    }
    });

    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
        // Canceled.
    }
    });

    alert.show();

Answer 1

Public void showToast() {
    Toast.makeText(this, R.string.no_name_given, Toast.LENGTH_SHORT).show();
} 

只需调用此方法，而不是在代码中显示类似的警报对话框中的toast。

else {
    showToast();
}

若要保持打开，请使用以下方法

public void forceOpen() {

    AlertDialog.Builder alert = new AlertDialog.Builder(this);

    alert.setTitle(R.string.save_game);
    alert.setMessage(R.string.request_name);

    // Set an EditText view to get user input 
    final EditText input = new EditText(this);
    input.setHint(R.string.untitled);
    alert.setView(input);

    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            String value = input.getText().toString();
            if(value != null) {
                // Do something with value      
            }
            else {
                Toast.makeText(context, R.string.no_name_given, Toast.LENGTH_SHORT).show();
            }
        }
    });

    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            // Canceled.
        }
    });

    alert.show();

}

只要重新打开..不知道为什么它会关闭，但这会工作
