    <p>I've got an Activity where y have 3 seekbar and I see each seekbar's value on each seekbar's textview.</p> <p>Now, I want to store each seekbar's value with sharedPreferences. I've tryed it in several ways, but i'm not able to get it.</p> <p>I've readed that the corret way to do it is to save the values when calling onPause, and to restore them when calling onResume.</p> <pre><code>public class Configuration extends Activity implements OnSeekBarChangeListener { public TextView progress1; public TextView progress2; public TextView progress3; private SeekBar bar1; private SeekBar bar2; private SeekBar bar3; private int savedProgress1; private int savedProgress2; private int savedProgress3; private int loadedProgress1; private int loadedProgress2; private int loadedProgress3; private String Key_PROGRESS_1 = "bar1_progress"; private String Key_PROGRESS_2 = "bar2_progress"; private String Key_PROGRESS_3 = "bar3_progress"; SharedPreferences mPreferences; SharedPreferences.Editor editor; /********************* * * ONCREATE * ********************/ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.configuracion2); bar1 = (SeekBar)findViewById(R.id.fast_bar); //make seekbar object bar1.setOnSeekBarChangeListener(this); //set seekbar listener progress1 = (TextView)findViewById(R.id.salida1); bar2 = (SeekBar)findViewById(R.id.climb_bar); bar2.setOnSeekBarChangeListener(this); progress2 = (TextView)findViewById(R.id.salida2); bar3 = (SeekBar)findViewById(R.id.platform_bar); bar3.setOnSeekBarChangeListener(this); progress3 = (TextView)findViewById(R.id.salida3); mPreferences = PreferenceManager.getDefaultSharedPreferences(this); editor = mPreferences.edit(); } public void onProgressChanged(SeekBar bar, int progress, boolean fromUser) { Log.v("", "" + bar); switch (bar.getId()) { case R.id.fast_bar: progress1.setText(progress + "%"); break; case R.id.climb_bar: progress2.setText(progress + "%"); break; case R.id.platform_bar: progress3.setText(progress + "%"); break; } } @Override public void onStartTrackingTouch(SeekBar seekBar) { } @Override public void onStopTrackingTouch(SeekBar seekBar) { seekBar.setSecondaryProgress(seekBar.getProgress()); } protected void onResume() { super.onResume(); loadedProgress1 = mPreferences.getInt("Key_PROGRESS_1", 0); bar1.setProgress(loadedProgress1); loadedProgress2 = mPreferences.getInt("Key_PROGRESS_2", 0); bar2.setProgress(loadedProgress2); loadedProgress2 = mPreferences.getInt("Key_PROGRESS_3", 0); bar3.setProgress(loadedProgress3); } protected void onPause(/*SeekBar seekBar*/) { super.onPause(); savedProgress1 = bar1.getProgress(); editor.putInt(Key_PROGRESS_1, savedProgress1); savedProgress2 = bar2.getProgress(); editor.putInt(Key_PROGRESS_2, savedProgress2); savedProgress3 = bar3.getProgress(); editor.putInt(Key_PROGRESS_3, savedProgress3); editor.commit(); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
