我正在使用 TabView
并在其中使用 Fragment
来加载每个选项卡。我想在用户触摸任何 fragment 时获取 Touch
事件。
fragment 代码
public MobileBankingFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
context = (FragmentActivity) super.getActivity();
view = inflater.inflate(R.layout.fragment_mobile_banking, container, false);
alarm = new TimerReceiver();
init(view);
touchListener(view);
return view;
}
private void touchListener(View view) {
layout= (FrameLayout) view.findViewById(R.id.fragmentMobileBanking);
layout.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(context, "you just touch the screen :-)", Toast.LENGTH_SHORT).show();
return true;
}
});
view.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(context, "you just touch the screen :-)", Toast.LENGTH_SHORT).show();
startTheTimerForTenSecond();
return true;
}
});
}
这里我尝试通过两种方式获取触摸事件,一种是通过事件,另一种是通过布局的 id,但我一直没有成功。此代码没有错误,但也没有输出。
最佳答案
对我有用:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_take_attendance, container, false);
touchListener(view);
..
}
private void touchListener(View view) {
view.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getActionMasked() == MotionEvent.ACTION_DOWN){
Toast.makeText(getActivity(), "you just touch the screen :-)", Toast.LENGTH_SHORT).show();
}
return true;
}
});
}
当你触摸整个 fragment 时它会听
关于android - setOnTouchListener 不适用于 android fragment ,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/29535948/
