我想在我的应用上显示键盘时移动我的布局。我使用了adjustResize,adjustPan和它们两个用于活动,但没有它们工作,它仍然在窗体上显示键盘,并且不移动上面的布局。

这是我的布局:

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

          ............... my views 

        </LinearLayout>
    </ScrollView>
</RelativeLayout>

我怎样才能使它有效?

答案 0 :(得分:1)

试试这个

final View activityRootView = findViewById(R.id.activityRoot);
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
                if (heightDiff > dpToPx(getApplicationContext(), 200)) { // if more than 200 dp, it's probably a keyboard...
                    // ... do something here
                }
            }
        });


 public static float dpToPx(Context context, float valueInDp) {
        DisplayMetrics metrics = context.getResources().getDisplayMetrics();
        return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, valueInDp, metrics);
    }

并且只需在xml中添加 机器人:ID =&#34; @ + ID / activityRoot&#34;

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    **android:id="@+id/activityRoot"**>

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

          ............... my views 

        </LinearLayout>
    </ScrollView>
</RelativeLayout>
