我在RelativeLayout中使用滚动视图,我将onClickLIstener分配给RelativeLayout。
我正在使用以下代码。 Layoutfile
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/row2_lnr_layout_ver">
<ScrollView
android:id="@+id/row2_scrollview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fadeScrollbars="false"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbars="vertical"
android:fillViewport="true">
<TextView
android:id="@+id/sa_sub_txt_view_2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="10dp"
android:layout_weight="0.4"
android:paddingLeft="10dp"
android:text="hjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj"
android:textColor="@android:color/black">
</TextView>
</ScrollView>
</RelativeLayout>
OnCreate()中的Java文件
((RelativeLayout)findViewById(R.id.row2_lnr_layout_ver)).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.i("MainActivity", "onSmartActionClicked");
Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_SHORT).show();
}
});
因此,当我单击TextView或scrollview时,它不会显示Toast。但是当我删除滚动视图并单击textview时,它工作正常。任何人都可以告诉我为什么这个奇怪的行为在使用ScrollView ??

是否可以尝试为TextView添加以下触摸侦听器,之后,为Textview设置onclick Listener,而不是将其提供给相对布局。
private OnTouchListener textViewTouchListener= new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
v.getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_MOVE:
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
case MotionEvent.ACTION_UP:
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
v.onTouchEvent(event);
return true;
}
};

从ViewParent尝试requestDisallowInterceptTouchEvent:http://developer.android.com/reference/android/view/ViewParent.html#requestDisallowInterceptTouchEvent(boolean)
public boolean onTouchEvent(MotionEvent ev) {
if (ev.getAction() == MotionEvent.ACTION_DOWN) {
this.getParent().requestDisallowInterceptTouchEvent(true);
}
if (ev.getAction() == MotionEvent.ACTION_UP) {
this.getParent().requestDisallowInterceptTouchEvent(false);
}
return super.onTouchEvent(ev);
}
