Many long people would certainly say to View add Padding on the line Well, yes, this would solve the problem, but have you ever wondered if the View has a background image, the results you added a Padding, View background image deformation, and this under the scope of the case to increase clicks by adding Padding scheme will not work, how to crack? In fact, very simple A little brains to put this issue is resolved, we give the little button or peripheral wrapped in a LinearLayout RelativeLayout, when we click on the periphery of LinearLayout or RelativeLayout when this event to pass small button immediately to solve the problem

Key Code:

public class FatArrowView extends RelativeLayout {
//拦截事件
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {（ http://www.my516.com）
Log.v(TAG,"onInterceptTouchEvent start...");
return true;
}

// The event distributed to our children CheckBox View
@Override
public boolean onTouchEvent (MotionEvent Event) {
Log.v (TAG, "onTouchEvent Start ...");
// When the finger leaves the screen to set the CheckBox state
if ( event.getAction () == MotionEvent.ACTION_UP) {
ischeck = ischeck;!
mCheckBox.setChecked (ischeck);
}
return to true;
}
}
