I am first time asking question,please solve my problem. I am developing small Music player App. in that I've facing a silly problem,i searched on google a lot but still it is. I am using listfragment to show the list of songs.Now the problem is when i set list item background to transparent it works.But as soon as i scroll the list the list background changes to system default background. I am new to android,Please help me... I tried these already in my layout files: <pre><code>android:background="@android:color/transparent" android:cacheColorHint="#00000000" </code></pre> My main activity code is: <pre><code> package com.android.player; import in.wptrafficanalyzer.viewpagerdemo.R; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; import android.support.v4.view.ViewPager; import android.view.Menu; public class MainActivity extends FragmentActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); /** Getting a reference to the ViewPager defined the layout file */ ViewPager pager = (ViewPager) findViewById(R.id.pager); /** Getting fragment manager */ FragmentManager fm = getSupportFragmentManager(); /** Instantiating FragmentPagerAdapter */ MyFragmentPagerAdapter pagerAdapter = new MyFragmentPagerAdapter(fm); /** Setting the pagerAdapter to the pager object */ pager.setAdapter(pagerAdapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu);

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.
