设置背景图像警报对话框 [英] set background image alertdialog

问题描述

我正在尝试使用Buttons和RadioGroup创建自定义的AlertDialog.我想为此AlertDialog将背景图像保存在我的可绘制对象中.

I am trying to create a customized AlertDialog with Buttons and RadioGroup. I want to have a background image saved in my drawable for this AlertDialog.

AlertDialog.Builder alert = new AlertDialog.Builder(AutoGenerate.this);                    
alert.setTitle("Select color");

还有像alert.setbackgrounddrawable(R.drawable.img)这样的其他选择吗?

Is there any alternative option like alert.setbackgrounddrawable(R.drawable.img)?

推荐答案

带有自定义视图的自定义对话框.

Custom dialog with custom view.

    Dialog d = new Dialog(AutoGenerate.this);
    d.requestWindowFeature(Window.FEATURE_NO_TITLE);
    d.setContentView(R.layout.alertdialog);// custom layour for dialog.
    Button thankyou = (Button) d.findViewById(R.id.thankyou);
    d.show();

alertdialog.xml

    rb= (RadioButton) findViewById(R.id.radioButton1);
    rb.setOnClickListener(new OnClickListener()

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            showAlertDialog();
        }

    });       

     public void showAlertDialog() {

        final Dialog d = new Dialog(MainActivity.this);
        d.requestWindowFeature(Window.FEATURE_NO_TITLE);
        d.setContentView(R.layout.alertdialog);
        // Thank you Button Listener.
        final TextView tv = (TextView) d.findViewById(R.id.textView1);
        final Button thankyou = (Button) d.findViewById(R.id.thankyou);
        thankyou.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View arg0, MotionEvent event) {
                // TODO Auto-generated method stub
                      tv.setText("Button Clicked");

                return true;
            }

        });

        d.show();
    }
