我试图修改你的布局。尝试这可能会对你有所帮助..只需创建一个新的XML布局文件，并检查它是否适合你。

我的自定义适配器类是在这里。 ：
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;
}
}
我的活动类是在这儿，我很创建自定义适配器对象，
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);
}
});
}
}
不工作就不能滚动列表出来列表框 的我只能看到5个项目 – Korkiat
由于listview有自己的滚动条，所以我认为它应该滚动listview而不用滚动按钮底部和textview顶部。如果你想用你的listview滚动它们，那么只需添加bottons作为页脚... –
我已检查它是否正常工作...如果你想检查，我张贴我的代码。只需创建新项目并尝试使其工作。 –
