java - 无法将搜索栏与文本关联起来

Question

我正在尝试将我的搜索栏与文本联系起来。在帮助下，我尝试这样做，但我的尝试没有成功。

此外，我还想在下面的代码中包含一个范围搜索栏，但不确定如何解决。任何帮助将不胜感激。

public class ProfileCreation extends Activity {

    private static final int RESULT_LOAD_IMAGE = 1;
    FrameLayout layout;
    Button save;

        setContentView(R.layout.activity_profile_creation);
        save = (Button) findViewById(R.id.button2);
        String picturePath = PreferenceManager.getDefaultSharedPreferences(this).getString("picturePath", "");
        if (!picturePath.equals("")) {
            ImageView imageView = (ImageView) findViewById(R.id.profilePicturePreview);
            imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
        }


        Button buttonLoadImage = (Button) findViewById(R.id.btnPictureSelect);

Answer 1

以下代码 fragment 应移出onClickListener。写在onCreate

中

 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 
        }
    });
