Android 在导航抽屉项目上，单击弹出窗口

@Override
public void onNavigationDrawerItemSelected(int position) {

    switch(position)
    {

        case 0:
            mTitle = getString(R.string.history);
            fragment_ride_history = new ListView(this);
            popupWindow = new PopupWindow(
                    fragment_ride_history,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(newBitmapDrawable());
            popupWindow.showAtLocation(new LinearLayout(this), Gravity.END, 10, 10);
            popupWindow.update(50, 50, 1500, 900);
            popupWindow.setContentView(fragment_ride_history);
            // this is to call webservice and append the data on listview
            getData(1);
            fragment_ride_history.setOnScrollListener(new 
            break;
   }
}

我想开发一个导航抽屉，然后在导航栏上单击我想显示一个附加到特定导航项目的弹出窗口（导航抽屉必须保持打开状态） 如果有人实现了这一点，请提供链接

@Override
public void onNavigationDrawerItemSelected(int position) {

    switch(position)
    {

        case 0:
            mTitle = getString(R.string.history);
            fragment_ride_history = new ListView(this);
            popupWindow = new PopupWindow(
                    fragment_ride_history,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(newBitmapDrawable());
            popupWindow.showAtLocation(new LinearLayout(this), Gravity.END, 10, 10);
            popupWindow.update(50, 50, 1500, 900);
            popupWindow.setContentView(fragment_ride_history);
            // this is to call webservice and append the data on listview
            getData(1);
            fragment_ride_history.setOnScrollListener(new 
            break;
   }
}

这是我的代码片段

@Override
public void onNavigationDrawerItemSelected(int position) {

    switch(position)
    {

        case 0:
            mTitle = getString(R.string.history);
            fragment_ride_history = new ListView(this);
            popupWindow = new PopupWindow(
                    fragment_ride_history,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(newBitmapDrawable());
            popupWindow.showAtLocation(new LinearLayout(this), Gravity.END, 10, 10);
            popupWindow.update(50, 50, 1500, 900);
            popupWindow.setContentView(fragment_ride_history);
            // this is to call webservice and append the data on listview
            getData(1);
            fragment_ride_history.setOnScrollListener(new 
            break;
   }
}

在“onNavigationDrawerItemSelected”上显示“popupWindow”没有问题

@Override
public void onNavigationDrawerItemSelected(int position) {

    switch(position)
    {

        case 0:
            mTitle = getString(R.string.history);
            fragment_ride_history = new ListView(this);
            popupWindow = new PopupWindow(
                    fragment_ride_history,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(newBitmapDrawable());
            popupWindow.showAtLocation(new LinearLayout(this), Gravity.END, 10, 10);
            popupWindow.update(50, 50, 1500, 900);
            popupWindow.setContentView(fragment_ride_history);
            // this is to call webservice and append the data on listview
            getData(1);
            fragment_ride_history.setOnScrollListener(new 
            break;
   }
}

我认为“setBackgroundDrawable”的问题是因为您的代码与我一起工作，所以我只是删除了

setBackgroundDrawable

我补充说

@Override
public void onNavigationDrawerItemSelected(int position) {

    switch(position)
    {

        case 0:
            mTitle = getString(R.string.history);
            fragment_ride_history = new ListView(this);
            popupWindow = new PopupWindow(
                    fragment_ride_history,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(newBitmapDrawable());
            popupWindow.showAtLocation(new LinearLayout(this), Gravity.END, 10, 10);
            popupWindow.update(50, 50, 1500, 900);
            popupWindow.setContentView(fragment_ride_history);
            // this is to call webservice and append the data on listview
            getData(1);
            fragment_ride_history.setOnScrollListener(new 
            break;
   }
}

fragment_ride_history.setBackgroundColor

测试是否首先不调用webservice

@Override
public void onNavigationDrawerItemSelected(int position) {

    switch(position)
    {

        case 0:
            mTitle = getString(R.string.history);
            fragment_ride_history = new ListView(this);
            popupWindow = new PopupWindow(
                    fragment_ride_history,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(newBitmapDrawable());
            popupWindow.showAtLocation(new LinearLayout(this), Gravity.END, 10, 10);
            popupWindow.update(50, 50, 1500, 900);
            popupWindow.setContentView(fragment_ride_history);
            // this is to call webservice and append the data on listview
            getData(1);
            fragment_ride_history.setOnScrollListener(new 
            break;
   }
}

对于webservice，请尝试从AsyncTask调用它，或者您可以使用凌空库并在调用响应时显示popupwindow，以不显示空的listview。

popupwindow.ShowAs下拉列表（anchorview，0，0，Gravity.RIGHT）；一点。我正在查找图像链接中显示的视图。是的，仅用于显示弹出窗口是可以的，但我正在查找图像链接中的视图。ThnX您不需要关闭navigationDrawer并更新popupWindow.showAtLocation（新的LinearLayout（此），Gravity.END，10，10）；更新（501500900）；将新的LinearLayout（此）删除到抽屉布局，并更新x、y、heightYes的值，它应该像在可展开视图中一样附着到抽屉项目。

@Override
public void onNavigationDrawerItemSelected(int position) {

    switch(position)
    {

        case 0:
            mTitle = getString(R.string.history);
            fragment_ride_history = new ListView(this);
            popupWindow = new PopupWindow(
                    fragment_ride_history,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(newBitmapDrawable());
            popupWindow.showAtLocation(new LinearLayout(this), Gravity.END, 10, 10);
            popupWindow.update(50, 50, 1500, 900);
            popupWindow.setContentView(fragment_ride_history);
            // this is to call webservice and append the data on listview
            getData(1);
            fragment_ride_history.setOnScrollListener(new 
            break;
   }
}
