在布局根节点加上下面三行
android:id="@+id/view_parent"
android:clickable="true"
android:focusableInTouchMode="true"
在代码中监听view_parent的FocusChangeListener事件
view_parent.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean b) {
if(b){
InputMethodManager manager = ((InputMethodManager)mActivity.getSystemService(mActivity.INPUT_METHOD_SERVICE));
if (manager != null)
manager.hideSoftInputFromWindow(view.getWindowToken(),InputMethodManager.HIDE_NOT_ALWAYS);
}
}
});
