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;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
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);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
save.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// Locate the image in res >
Bitmap bitmap = BitmapFactory.decodeFile("picturePath");
// Convert it to byte
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// Compress image to lower quality scale 1 - 100
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
Object image = null;
try {
String path = null;
image = readInFile(path);
} catch (Exception e) {
e.printStackTrace();
}
// Create the ParseFile
ParseFile file = new ParseFile("picturePath", (byte[]) image);
// Upload the image into Parse Cloud
file.saveInBackground();
// Create a New Class called "ImageUpload" in Parse
ParseObject imgupload = new ParseObject("Image");
// Create a column named "ImageName" and set the string
imgupload.put("Image", "picturePath");
// Create a column named "ImageFile" and insert the image
imgupload.put("ImageFile", file);
// Create the class and the columns
imgupload.saveInBackground();
// Show a simple toast message
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
}
});
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.profilePicturePreview);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
private byte[] readInFile(String path) throws IOException {
// TODO Auto-generated method stub
byte[] data = null;
File file = new File(path);
InputStream input_stream = new BufferedInputStream(new FileInputStream(
file));
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
data = new byte[16384]; // 16K
int bytes_read;
while ((bytes_read = input_stream.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, bytes_read);
}
input_stream.close();
return buffer.toByteArray();
}
}
更新了代码

super.onCreate(savedInstanceState);

imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
SeekBar seekBar = (SeekBar) findViewById(R.id.seekBarDistance);

最佳答案
以下代码 fragment 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
}
});
