如何從xml引用圖片？

Question

這是從我的應用程序創建。

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

    getWindow().setFormat(PixelFormat.UNKNOWN); 
    surfaceView = (SurfaceView)findViewById(R.id.camerapreview); 
    surfaceHolder = surfaceView.getHolder(); 
    surfaceHolder.addCallback(this); 
    surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 

    controlInflater = LayoutInflater.from(getBaseContext()); 
    View viewControl = controlInflater.inflate(R.layout.control, null); 
    //ImageView img = (ImageView)controlInflater. 
    LayoutParams layoutParamsControl 
     = new LayoutParams(LayoutParams.FILL_PARENT, 
     LayoutParams.FILL_PARENT); 
    this.addContentView(viewControl, layoutParamsControl); 

} 

control.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:gravity="center" 
     > 
<ImageView 
    android:id="@+id/img" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:background="@drawable/ic_launcher" 
    /> 

</LinearLayout> 

如何從Java代碼引用的ImageView在control.xml。

Answer 1

View viewControl = controlInflater.inflate(R.layout.control, null); 
ImageView img =(ImageView) viewControl.findViewById(R.id.img); 

用這個來獲得對imageView的引用。

Answer 2

有在查看一個findViewById方法，以及：

ImageView img = (ImageView)viewControl.findViewById(R.id.img)
