示例1: setupFrameLayout
import android.view.ViewGroup; //導入方法依賴的package包/類
private void setupFrameLayout(){
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
ViewGroup contentArea = (ViewGroup) mActivity.getWindow().getDecorView().findViewById(android.R.id.content);
int [] pos = new int[2];
contentArea.getLocationOnScreen(pos);
// frameLayoutWithHole's coordinates are calculated taking full screen height into account
// but we're adding it to the content area only, so we need to offset it to the same Y value of contentArea
layoutParams.setMargins(0,-pos[1],0,0);
contentArea.addView(mFrameLayout, layoutParams);
}
示例2: onInterceptTouchEvent
import android.view.ViewGroup; //導入方法依賴的package包/類
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {

switch (ev.getAction()) {

int x = (int) ev.getX();

break;
}
