Question

有谁知道为什么我的搜索栏监听器没有从搜索栏中获取任何数据？我有所有设置和工作，但它没有更新textviews，我认为它与弹出窗口有关，使用不同的活动布局到它所在的活动

public class Environment extends Activity implements OnSeekBarChangeListener
{

private ImageButton lockButton;


SeekBar bar;
TextView textProgress, textAction;
private PopupWindow pwindo;


@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.setup_environment);

    lockButton = (ImageButton) findViewById(R.id.lock);
    lockButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {
            initiatePopupWindow();

        }
    });

}


private void initiatePopupWindow() {
    try {
        LayoutInflater inflater = (LayoutInflater) Environment.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.annotation,
                (ViewGroup) findViewById(R.id.popup_element));
        pwindo = new PopupWindow(layout, 1000, 1200, true);
        pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);

        bar = (SeekBar)findViewById(R.id.seekBar1); // make seekbar object
        bar.setOnSeekBarChangeListener(this);
        textProgress = (TextView)findViewById(R.id.textViewProgress);

        textAction = (TextView)findViewById(R.id.textViewAction);

    } catch (Exception e) {
        e.printStackTrace();
    }
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,
                              boolean fromUser) {
    // TODO Auto-generated method stub

    textProgress.setText("The value is: "+progress);

    textAction.setText("changing");
}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
    textAction.setText("starting to track touch");

}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
    seekBar.setSecondaryProgress(seekBar.getProgress());
    textAction.setText("ended tracking touch");
}

} 每当我使用滑块时，它应该使用int值0-100更新，具体取决于滑块的位置，如果我创建一个活动并立即使用它，它可以工作，但是当我把它放在一个弹出窗口时，它什么都不做？ / p>

试试这个，您应该通过布局中的视图初始化您的Seekbar等。只需执行findViewById即可搜索活动中的视图

private void initiatePopupWindow() {
    try {
        LayoutInflater inflater = (LayoutInflater) Environment.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.annotation,
                (ViewGroup) findViewById(R.id.popup_element));
        pwindo = new PopupWindow(layout, 1000, 1200, true);
        pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);

        bar = (SeekBar)layout.findViewById(R.id.seekBar1); // make seekbar object
        bar.setOnSeekBarChangeListener(this);
        textProgress = (TextView)layout.findViewById(R.id.textViewProgress);

        textAction = (TextView)layout.findViewById(R.id.textViewAction);

    } catch (Exception e) {
        e.printStackTrace();
    }
}

Android PopupWindow和SeekBar监听器没有响应
