我试图显示进度对话框并得到它,但现在想知道如何为进度对话框设置背景颜色,并且必须为进度条设置颜色。任何帮助赞赏我的代码

public class MainActivity extends Activity {

ProgressDialog progress;
Button b;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    b=(Button)findViewById(R.id.button1);


    b.setOnClickListener(new OnClickListener() {

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

            progress= new ProgressDialog(MainActivity.this);
            progress.setMessage("Loading...!");
            progress.show();

        }
    });

}}

XML 代码

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="164dp"
    android:text="Start"/>
