问题描述
我在底部显示了以下 activity_main.xml.在那里,出现了一个 CoordinatorLayout 和两个 LinearLayouts.第一个 LinearLayout1 有一个 EditText 来输入一些文本,并带有一个按钮来发送它.第二个有另外两个按钮.
I have the following activity_main.xml shown at bottom. There, a CoordinatorLayout and two LinearLayouts occur. The first LinearLayout1 has an EditText to input some text, with a button to send it. The second one has two other buttons.
如果我点击 EditText,键盘会出现,并使 LinearLayout2 中的所有内容几乎不可见.所以,我想在键盘打开时隐藏最后一个布局中的两个按钮.
If i click into the EditText, the keyboard shows up and makes everything in LinearLayout2 barely visible. So, i want to hide both buttons in last layout when keyboard is open.
我已经发现使用 android:windowSoftInputMode="stateHidden" 可能是诀窍,但仅与 AndroidManifest.xml 中的活动有关.我只想在第二个线性布局中使用这个内部.已经尝试在那里使用它,但没有成功.
I already found out to use android:windowSoftInputMode="stateHidden" may be the trick, but only in connection with activities in AndroidManifest.xml. I just want to use this inner the second linear layout. Already tried to use it there, but with no success.
此外,我要在我的 xml 中处理这个问题并保持我的 MainActivity 代码干净.这有什么可能吗?
In addition, i what to handle this in my xml and keep my MainActivity-code clean. Any possibilities for this?
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"> ... <android.support.design.widget.CoordinatorLayout> <android.support.v7.widget.RecyclerView/> </android.support.design.widget.CoordinatorLayout> <LinearLayout> <EditText/> <Button android:id="@+id/button_send"/> </LinearLayout> <LinearLayout> <Button/> <Button/> </LinearLayout> </LinearLayout>
推荐答案
我们过去也遇到过同样的问题,所以我们在完整布局对象上放置了一些 observable试试这个,让我知道
We had same issue in past so we have put some observable on full layout object try this and let me know
/*Hide button when keyboard is open*/ view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { Rect r = new Rect(); view.getWindowVisibleDisplayFrame(r); int heightDiff = view.getRootView().getHeight() - (r.bottom - r.top); if (heightDiff > 244) { // if more than 100 pixels, its probably a keyboard... //ok now we know the keyboard is up... buttonLayout.setVisibility(View.GONE); } else { //ok now we know the keyboard is down... buttonLayout.setVisibility(View.VISIBLE); } } });
