WebView 设置背景透明

先看效果;




代码:
布局:
<?xml version="1.0" encoding="UTF-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="@drawable/webtest"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

    <WebView android:id="@+id/web"
        android:background="@drawable/back_nocorner"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>
</AbsoluteLayout>


java代码:
public class MainActivity extends Activity{
  private Button button;
  private MyView view;
  WebView webView;
  @Override 
  public void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
    setContentView(R.layout.main);
    webView = (WebView)findViewById(R.id.web);
    //Drawable = getResources().getDrawable(R.drawable.back_nocorner);
   // webView.setBackgroundDrawable(getResources().getDrawable(R.drawable.back_nocorner));
    webView.setBackgroundColor(0);
    webView.loadUrl("file:///android_asset/storytext_py.html");
    }
}


修改后:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="@drawable/webtest"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

    <WebView android:id="@+id/web"
        android:background="@drawable/back_nocorner"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="30dp"
    android:layout_width="280dp"
    android:layout_height="60dp"/>
</FrameLayout>
