Question

我使用AlertDialog使用xml文件显示一些数据。但是当我在AlertDialog中膨胀xml时，默认按钮不会显示。请帮忙

Answer 1

只需在xml文件中添加新按钮，然后获取该按钮的ID，并将click监听器放在此按钮上。这对我有用。

    LayoutInflater factory = LayoutInflater.from(Splash.this);
    final View textEntryView = factory.inflate(R.layout.text_entry, null);

    //text_entry is an Layout XML file containing two text field to display in alert dialog

     final EditText input1 = (EditText) textEntryView.findViewById(R.id.editText1);
    final EditText input2 = (EditText) textEntryView.findViewById(R.id.editText2);             
                     input1.setHint("roomnumber");
                     input2.setHint("hotelname");
                     AlertDialog.Builder alert = new AlertDialog.Builder(Splash.this);

                     alert.setIcon(android.R.drawable.ic_menu_info_details)
                          .setTitle("Enter the Text:")
                          .setView(textEntryView)
                          .setPositiveButton("Your Default button text", 
                              new DialogInterface.OnClickListener() {
                                  public void onClick(DialogInterface dialog, int whichButton) {
                                         Log.i("AlertDialog","TextEntry 1 Entered "+input1.getText().toString());
                                         Log.i("AlertDialog","TextEntry 2 Entered "+input2.getText().toString());
                                         if(isOnline())
                                        {       
                                        /* User clicked OK so do some stuff */

                                  }else{


                                  }
                                  }
                              });

                     alert.show();

这将解决您的问题！您需要将onclick侦听器设置为对话框中的所有按钮。请遵循以下代码。

  public void showDialogWithIcons() {
            final Dialog dialog = new Dialog(this);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setContentView(R.layout.icons_dialog);

            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));

            Button yesButton = (Button) dialog.findViewById(R.id.yesanswer_icons);
            yesButton.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {

                    TextView tvForIconToChange = (TextView) findViewById(R.id.textInThePicture);
                    tvForIconToChange.setTypeface(tf);
                    tvForIconToChange.setText(getMyTextForIcon());
                    dialog.dismiss();

                }

            });
            dialog.show();
        }

Answer 4

因为它的自定义布局。要在自定义对话框中使用按钮，请在ur自定义布局xml中定义按钮，然后在代码中执行以下操作：

Button xyz = (Button)dialog.findViewbyId(R.id.abc)
xyz.setOnClickListener(this or new View.OnClickListener)

警报对话框的默认按钮在Android中不起作用
