Question

我使用这个代码，当我弹出一个键盘时，我在这里使文本视图消失了。但是当隐藏键盘时，我希望textview再次回到正常位置。此外，当textview消失时，它下面的edittext将会上升。然后在隐藏键盘时返回其正常位置。我怎样才能做到这一点？谢谢！

final View activityRootView = findViewById(R.id.LinearLayout1);
    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
            if (heightDiff > 100)  // if more than 100 pixels, its probably a keyboard...
                findViewById(R.id.titleTextView).setVisibility(View.GONE);

         }
    });

Answer 1

if (heightDiff > 100)  {
                findViewById(R.id.titleTextView).setVisibility(View.GONE);
      }else{
            findViewById(R.id.titleTextView).setVisibility(View.VISIBLE);
      }

应该这样做。

Answer 2

很简单 - 如果键盘显示超过100，键盘隐藏时应该小于100：

if (heightDiff > 100){  // if more than 100 pixels, its probably a keyboard...

    findViewById(R.id.titleTextView).setVisibility(View.GONE);

}else{

    findViewById(R.id.titleTextView).setVisibility(View.VISIBLE);

}

修改

试试这个：

if (heightDiff > 200){ // if more than 100 pixels, its probably a keyboard... findViewById(R.id.titleTextView).setVisibility(View.GONE); }else if(heightDiff < 200){ findViewById(R.id.titleTextView).setVisibility(View.VISIBLE); }

键盘弹出或隐藏时显示和删除TextView / Image
