Question

对于我的应用程序，我使用的是手风琴布局，其中我有三个面板，我正在尝试将面板（texview）大小设置为适合设备高度的大小。当这种情况发生变化时，这不起作用屏幕方向。我的视图大小不会根据设备在横向时的高度而改变。请帮我这个。

这是我的代码

if(layoutView.getId() == R.id.Advertitletext)
{
    openLayout = panel1;
    v = panel1.getVisibility();

    hideThemAll();
    if(v != View.VISIBLE)
    {
        panel1.setVisibility(View.VISIBLE);
        params = advertoutput.getLayoutParams();
        params.height = parentLinear.getHeight()-msgrecvtitle.getHeight()-msgsenttitle.getHeight()-mLogCheck.getHeight()-PearActivity.peartabs.getHeight();
        advertoutput.setLayoutParams(params);
    }

}

这是我的onConfiguration（）方法

@Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        ViewTreeObserver observer = parentLinear.getViewTreeObserver();
        observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

            @Override
            public void onGlobalLayout() {

                parentLinear.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                if(openLayout==panel1){
                    params = advertoutput.getLayoutParams();
                    params.height = parentLinear.getHeight()-msgrecvtitle.getHeight()-msgsenttitle.getHeight()-mLogCheck.getHeight()-PearActivity.peartabs.getHeight();
                    advertoutput.setLayoutParams(params);
                }
                else if(openLayout == panel2){
                    params = msgrecvoutput.getLayoutParams();
                    params.height = parentLinear.getHeight()-adverttitle.getHeight()-msgsenttitle.getHeight()-mLogCheck.getHeight()-PearActivity.peartabs.getHeight();
                    msgrecvoutput.setLayoutParams(params);

                }else   if(openLayout == panel3){
                    params = msgsentoutput.getLayoutParams();
                    params.height = parentLinear.getHeight()-adverttitle.getHeight()-msgrecvtitle.getHeight()-mLogCheck.getHeight()-PearActivity.peartabs.getHeight();
                    msgsentoutput.setLayoutParams(params);
                }

            }
        });

    }

如果您在AndroidManifest文件中包含您需要系统来处理方向更改：

android:configChanges="orientation"

您应该在onConfigurationChanged()中实现您的代码，否则它应该在onResume()内（因为活动暂停然后恢复，并且不会再次调用onCreate。

getHeight（）视图在Android中为纵向和横向提供相同的结果
