    <p>I want to select all check boxes in a listview but I'm not able to get checkbox objects from the listview. I can select a single check box but not multiple check boxes.</p> <p>Your suggestion are appreciable. </p> <p><em>Code:</em></p> <pre><code> public class MainActivity extends Activity { @Override public void onCreate(Bundle icicle) { super.onCreate(savedInstanceState); setContentView(R.layout.bir); mainListView = (ListView) findViewById(R.id.mainListView); selectall = (Button) findViewById(R.id.button1); selectall.setOnClickListener(this); save = (Button) findViewById(R.id.button2); save.setOnClickListener(this); mainListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; parent, View item, int position, long id) { } }); } } </code></pre> <p><em>class Amphian:</em></p> <pre><code> private static class Amphian { private String name = "" ; private boolean checked = false ; public Amphian( String name ) { this.name = name ; } public Amphian( String name, boolean checked ) { this.name = name ; this.checked = checked ; } public String getName() { return name; } public void setName(String name) { this.name = name; } public boolean isChecked() { return checked; } public void setChecked(boolean checked) { this.checked = checked; } @Override public String toString() { return name ; } public void toggleChecked() { checked = !checked ; } } </code></pre> <p><em>class AmphiansArrayAdapter:</em></p> <pre><code> public class AmphiansArrayAdapter extends ArrayAdapter&lt;Amphian&gt; { Integer name[] = { R.raw.ducks_landing_in_water, R.raw.flicker_chicks_feeding, R.raw.geese_honking_loud, R.raw.geese_honking_distant, R.raw.gold_finch, R.raw.humming_bird_feeding, R.raw.indigo_bunting, R.raw.loons, R.raw.little_blue_heron_fishing, R.raw.pelican_chick, R.raw.purple_martins, R.raw.red_winged_blackbird, R.raw.shorebirds_close, R.raw.shorebirds_distant, R.raw.shorebirds_misc, R.raw.shoreseabirds, R.raw.snow_geese_flock, R.raw.terns, R.raw.tufted_titmouse, R.raw.tundra_swans, R.raw.wood_stork_chicks, R.raw.woodpecker_tapping }; private final LayoutInflater inflater; public AmphiansArrayAdapter(Context context, List&lt;Amphian&gt; amphianList) { super( context, R.layout.simplerow, R.id.rowTextView, amphianList ); inflater = LayoutInflater.from(context) ; } @Override public View getView( final int position, View convertView , ViewGroup parent) { final Amphian amphian=this.getItem(position); mp=new MediaPlayer(); if ( convertView == null ) { convertView = inflater.inflate(R.layout.simplerow, null); // Find the child views. textView = (TextView) convertView.findViewById( R.id.rowTextView ); checkBox = (CheckBox) convertView.findViewById( R.id.checkBox1 ); button = (Button)convertView.findViewById(R.id.button1); // Optimization: Tag the row with it's child views, so we don't have to // call findViewById() later when we reuse the row. convertView.setTag( new AmphianViewHolder(textView,checkBox,button) ); // If CheckBox is toggled, update the planet it is tagged with. checkBox.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View v) { cb= (CheckBox) v; Log.e("cb",String.valueOf(cb)); Amphian amphian = (Amphian) cb.getTag(); Log.e("cb",String.valueOf(cb.getTag())); amphian.setChecked(cb.isChecked()); Log.e("dd", "ddd"); } }); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Button bu=(Button)v; Amphian amphian; //= (Amphian) bu.getTag(); //Log.e(String.valueOf(amphian),"ddd"); </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
