java - 无法将搜索栏与文本相关联

我正在尝试将我的搜索栏与文本相关联。在帮助下，我尝试这样做，但是我的尝试没有成功。

我也想在下面的代码中包含一个范围查找栏，但是不确定如何解决。任何帮助将不胜感激。

public class ProfileCreation extends Activity {

最佳答案

下面的代码段应移出onClickListener。写在onCreate

 SeekBar seekBar = (SeekBar) findViewById(R.id.seekBarDistance);
    final TextView seekBarValue = (TextView) findViewById(R.id.seekBarDistanceValue);

    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress,
            boolean fromUser) {
            // TODO Auto-generated method stub
            seekBarValue.setText(String.valueOf(progress));
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub
        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub
        }
    });
