下面是程序中的 oncreate 方法:
@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>
如何从java代码中的 control.xml 中引用 ImageView?
