レイアウトを変更しようとしました。これを試してみてください..新しいxmlレイアウトファイルを作成して、それが機能しているかどうかを確認してください.

私のカスタム アダプター クラスはこちらです。:
public class my_custom_adapter extends ArrayAdapter<String> {
private Context context = null;
String[] elements = null;
private ArrayList<Boolean> itemChecked = null;
public my_custom_adapter(Context context, int type, String[] elements2)
{
super(context, type, elements2);
this.elements = elements2;
this.context = context;
itemChecked = new ArrayList<Boolean>();
BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("master_check_change")) {
boolean check_value = intent.getBooleanExtra("check_value", false);
set_checked(check_value);
notifyDataSetChanged();
}
}
};
context.registerReceiver(receiver, new IntentFilter("master_check_change"));
set_checked(false);
}
// AS EVERY TIME LISTVIEW INFLATE YOUR VIEWS WHEN YOU MOVE THEM SO YOU NEED TO SAVE ALL OF YOUR CHECKBOX STATES IN SOME ARRAYLIST OTHERWISE IT WILL SET ANY DEFAULT VALUE.
private void set_checked(boolean is_checked)
{
for (int i=0; i < elements.length; i++) {
itemChecked.add(i, is_checked);
}
}
//THIS IS SIMPLY A CLASS VIEW WILL HOLD DIFFERENT VIEWS OF YOUR ROW.
static class ViewHolder
{
public TextView tv;
public CheckBox cb;
public ImageView iv;
}
@Override
public View getView (final int position, View convertView, ViewGroup parent)
{
View rowView = convertView;
ViewHolder holder = null;
if (rowView == null) {
LayoutInflater inflater = (LayoutInflater)context.getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
// HERE I AM INFLATING LISTVIEW LAYOUT.
rowView = inflater.inflate(R.layout.inflated_layout, null, false);
holder = new ViewHolder();
holder.cb = (CheckBox) rowView.findViewById(R.id.checkBox1);
holder.tv = (TextView) rowView.findViewById(R.id.textView1);
holder.iv = (ImageView) rowView.findViewById(R.id.imageView1);
rowView.setTag(holder);
} else {
holder = (ViewHolder) rowView.getTag();
}
if (holder != null) {
holder.tv.setText(elements[position]);
holder.cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
itemChecked.set(position, isChecked);
}
});
if(position < itemChecked.size()) {
holder.cb.setChecked(itemChecked.get(position));
}
}
return rowView;
}
}
私のアクティビティクラスはここにあり、カスタムアダプターオブジェクトを作成しています。
public class Test_stflowActivity extends Activity {
public CheckBox master_cb = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.temp_layout);
String[] elements = new String[10];
for (int i = 0; i < 10; i++) {
elements[i] = "elements " + i;
}
CheckBox master_cb = new CheckBox(getApplicationContext());
master_cb.setText("Check All");
//HERE IS THE LIST VIEW WHICH I HAVE CREATED IN MY XML FILE.
ListView lv = (ListView) findViewById(R.id.listView1);
//HERE I AM CREATING CUSTOM ADAPTER OBJECT.
my_custom_adapter adapter = new my_custom_adapter(this, android.R.layout.simple_list_item_1, elements);
lv.addHeaderView(master_cb);
lv.setAdapter(adapter);
master_cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
Intent my_intent = new Intent("master_check_change");
my_intent.putExtra("check_value", isChecked);
sendBroadcast(my_intent);
}
});
}
}
