我已阅读此问题的多篇帖子,解决方法是使用OnGlobalLayoutListener
。这里的问题是我的应用程序在清单中声明了以下内容:
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
因此输入模式调整不起作用,我无法使用OnGlobalLayoutListener
如何获得软输入可见/消失的事件,我还需要获得输入的高度以调整我的当前布局bottomMargin
。
感谢。

我不知道你如何使用OnGlobalLayoutListener
,但它在我的代码中运行良好:
final View activityRootView = findViewById(R.id.container);
final ViewTreeObserver observer = activityRootView
.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
// r will be populated with the coordinates of your view
// that area still visible.
activityRootView.getWindowVisibleDisplayFrame(r);
int heightDiff = activityRootView.getRootView().getHeight()
- (r.bottom - r.top);
Toast.makeText(TestActivity.this, String.valueOf(heightDiff),
Toast.LENGTH_SHORT).show();
}
});
以上代码位于我的TestActivity的onResume()
中,主题为@android:style/Theme.NoTitleBar.Fullscreen
视图的布局文件:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<EditText
android:id="@+id/textview"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="@+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="aaa" />
</LinearLayout>
menifest中的活动配置:
<activity
android:name=".ui.activity.TestActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

我用它来检测softInput的可见性。试试这个:
public boolean isKeyBoardVisible;
int previousHeightDiffrence = 0;
public void checkKeyboardHeight(final View parentLayout) {
parentLayout.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
parentLayout.getWindowVisibleDisplayFrame(r);
int screenHeight = parentLayout.getRootView()
.getHeight();
int heightDifference = screenHeight - (r.bottom);
if (previousHeightDiffrence - heightDifference > 50) {
// Keyboard is not visible
}
if (previousHeightDiffrence - heightDifference < -50) {
// Keyboard Visible
}
previousHeightDiffrence = heightDifference;
if (heightDifference > 100) {
isKeyBoardVisible = true;
} else {
isKeyBoardVisible = false;
}
}
});
}
这里parentLayout是我活动的最顶层布局,如果键盘可见,则heightDifference是我键盘的高度......

试试这个:
布局:
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<MyView
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
然后实现MyView
public class MyView extends View
{
public static int ScreenHeight;
@Override
public function onDraw(Canvas canvas){
if(ScreenHeight != canvas.getHeight()){
// this is your event
}
ScreenHeight = canvas.getHeight();
}
}
现在ScreenHeight
正是您要找的。 p>
