[英]How to hide widget when keyboard pops?
I have two ViewPager on the same view with weight= 70/30 . 我在同一视图上有两个ViewPager,其中weight = 70/30。 The problem is when the keyboard pops, my both view keep the same weight and do not display my EditText. 问题是当键盘弹出时,两个视图的权重保持不变,并且不显示我的EditText。

I think my last solution is to make disappear my picker at the top when my keyboard pops. 我认为我的最后一个解决方案是在键盘弹出时使选择器消失在顶部。 How can I do this? 我怎样才能做到这一点?
Try to use ScrollView
in parent view, for example- 尝试在父视图中使用ScrollView
,例如-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:fab="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true">
<ScrollView
android:id="@+id/scroll_view_parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:fillViewport="true"
android:scrollbars="none">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
..................................
type your code here
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorWhite"
android:orientation="vertical">
..................................
type your code here
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>
Hope this help you : 希望这对您有帮助:
public class YourActivity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_activity);
attachKeyboardListeners();
}
@Override
protected void onShowKeyboard(int keyboardHeight) {
// when keyboard is shown
yourWidget.setVisibility(View.GONE);
}
@Override
protected void onHideKeyboard() {
// when keyboard is hidden
yourWidget.setVisibility(View.VISIBLE);
}
}
You can set listeners when keyboard is opened and closed. 您可以在打开和关闭键盘时设置监听器。
// ContentView is the root view of the layout of this activity/fragment
contentView.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
contentView.getWindowVisibleDisplayFrame(r);
int screenHeight = contentView.getRootView().getHeight();
// r.bottom is the position above soft keypad or device button.
// if keypad is shown, the r.bottom is smaller than that before.
int keypadHeight = screenHeight - r.bottom;
Log.d(TAG, "keypadHeight = " + keypadHeight);
if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
// keyboard is opened
} else {
// keyboard is closed
}
}
});
