set background image alertdialog

问题

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");

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

回答1:

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

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/dialog_layout_root"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:orientation="vertical"
android:padding="10dp"
 >
<Button
    android:id="@+id/thankyou"
    android:layout_width="100dp"
    android:layout_height="60dp"
    android:layout_gravity="center_horizontal" 
    android:text="hello"

    android:padding="5dp">

          </Button>

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView" />

</LinearLayout>

Edit :

    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();
    }

you can do that using Layout file. Check Code Below

LayoutInflater inflater = (LayoutInflater) this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View dialoglayout = inflater.inflate(R.layout.dialog_layout, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);
builder.show();

dialog_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/ic_launcher" />

</LinearLayout>

You can also use diffrent views in xml.

You can set Icon to alert dialog like this

alert.setIcon(R.drawable.image);

回答5:

Yes, there is a relatively simple variant that works with an AlertDialog:

// your code above
AlertDialog.Builder alert = new AlertDialog.Builder(AutoGenerate.this);                    
alert.setTitle("Select color");
// first show the dialog, then access its window and there set the background
alert.show();
alert.getWindow().setBackgroundDrawable(R.drawable.img);
