    <p>I have written a custom preference class which contains a simple progress bar in it to allow setting things like volume. The preference worked great until I tried putting two of these preference in my preference screen. </p> <p>When I did that the preference screen started to act wierdly » the two custom preferences switch locations constantly as i drag the seek bar. </p> <p>Any one have any idea why this is happening? Thanks</p> <p>EDIT: here is the code of the custom preference</p> <pre><code>import android.content.Context; import android.content.SharedPreferences; import android.content.res.TypedArray; import android.graphics.Typeface; import android.preference.Preference; import android.util.AttributeSet; import android.view.Gravity; import android.view.View; import android.view.ViewGroup; import android.widget.LinearLayout; import android.widget.SeekBar; import android.widget.SeekBar.OnSeekBarChangeListener; import android.widget.TextView; public class SeekBarPreference extends Preference implements OnSeekBarChangeListener { private int mMaximum = 60; private int mInterval = 1; private int mMinimum = 1; private int mDefault = 50; private TextView monitorBox; public SeekBarPreference(Context context) { super(context); } public SeekBarPreference(Context context, AttributeSet attrs) { super(context, attrs); initValues(context, attrs); } public SeekBarPreference(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); initValues(context, attrs); } private void initValues(Context context, AttributeSet attrs) { TypedArray styledAttributes = context.obtainStyledAttributes(attrs, R.styleable.SeekBarPreference); mMinimum = styledAttributes.getInt( R.styleable.SeekBarPreference_barMinValue, 1); mMaximum = styledAttributes.getInt( R.styleable.SeekBarPreference_barMaxValue, 1); mInterval = styledAttributes.getInt( R.styleable.SeekBarPreference_barInterval, 1); mDefault = styledAttributes.getInt( R.styleable.SeekBarPreference_defaultValue, mMaximum); } @Override protected View onCreateView(ViewGroup parent) { LinearLayout horizontalLayout = new LinearLayout(getContext()); horizontalLayout.setPadding(15, 5, 10, 5); horizontalLayout.setOrientation(LinearLayout.HORIZONTAL); LinearLayout verticalLayout = new LinearLayout(getContext()); verticalLayout.setOrientation(LinearLayout.VERTICAL); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); layoutParams.gravity = Gravity.LEFT; layoutParams.weight = 0.5f; LinearLayout.LayoutParams settingTitleLayoutParams = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); settingTitleLayoutParams.gravity = Gravity.LEFT; settingTitleLayoutParams.weight = 1.0f; LinearLayout.LayoutParams seekbarLayoutParams = new LinearLayout.LayoutParams( 80, LinearLayout.LayoutParams.WRAP_CONTENT); seekbarLayoutParams.gravity = Gravity.RIGHT | Gravity.CENTER_VERTICAL; LinearLayout.LayoutParams selectedAmountLayoutParams = new LinearLayout.LayoutParams( 30, LinearLayout.LayoutParams.WRAP_CONTENT); selectedAmountLayoutParams.gravity = Gravity.CENTER; TextView titleTextView = new TextView(getContext()); titleTextView.setText(getTitle()); titleTextView.setTextSize(18); titleTextView.setTypeface(Typeface.SANS_SERIF, Typeface.BOLD); titleTextView.setGravity(Gravity.LEFT); titleTextView.setLayoutParams(settingTitleLayoutParams); TextView summeryTextView = new TextView(getContext()); summeryTextView.setText(getSummary()); summeryTextView.setTextSize(14); summeryTextView.setTypeface(Typeface.SANS_SERIF); summeryTextView.setGravity(Gravity.LEFT); summeryTextView.setLayoutParams(settingTitleLayoutParams); SeekBar bar = new SeekBar(getContext()); bar.setMax(mMaximum); bar.setProgress(mDefault); bar.setPadding(10, 0, 10, 0); bar.setLayoutParams(seekbarLayoutParams); bar.setOnSeekBarChangeListener(this); this.monitorBox = new TextView(getContext()); this.monitorBox.setTextSize(12); this.monitorBox.setTypeface(Typeface.MONOSPACE, Typeface.ITALIC); this.monitorBox.setLayoutParams(selectedAmountLayoutParams); this.monitorBox.setPadding(2, 5, 0, 0); this.monitorBox.setText(bar.getProgress() + ""); verticalLayout.addView(titleTextView); verticalLayout.addView(summeryTextView); horizontalLayout.addView(verticalLayout, layoutParams); horizontalLayout.addView(bar); horizontalLayout.addView(this.monitorBox); horizontalLayout.setId(android.R.id.widget_frame); return horizontalLayout; } public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { progress = Math.round(((float) progress) / mInterval) * mInterval; if (progress &lt; mMinimum) { progress = mMinimum; } if (!callChangeListener(progress)) { seekBar.setProgress((int) this.mDefault); return; } seekBar.setProgress(progress); this.mDefault = progress; this.monitorBox.setText(progress + ""); updatePreference(progress); notifyChanged(); } public void onStartTrackingTouch(SeekBar seekBar) { } public void onStopTrackingTouch(SeekBar seekBar) { } @Override protected Object onGetDefaultValue(TypedArray ta, int index) { int dValue = (int) ta.getInt(index, 5); return validateValue(dValue); } @Override protected void onSetInitialValue(boolean restoreValue, Object defaultValue) { int temp = restoreValue ?

I do not want to do this. anyone have any idea?</p>

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.
