Android 如何将按钮添加到列表视图？
我使用Android 如何将按钮添加到列表视图？,android,listview,Android,Listview,我使用ListActivity和Adapter创建了一个列表视图，我要做的是添加按钮。按钮的数量是动态的，事实上，在以前的活动中，用户可以设置要添加的按钮数量。所以我不能使用布局。下面给出了创建我的listView的代码 public class AppList extends ListActivity { private String[] mStrings = (String[]) GridViewAppInfoAdapter.lApplication .to
ListActivityAdapterpublic class AppList extends ListActivity {
private String[] mStrings = (String[]) GridViewAppInfoAdapter.lApplication
.toArray(new String[GridViewAppInfoAdapter.lApplication.size()]);
public void setApplication() {
for (int i = 0; i < GridViewAppInfoAdapter.lApplication.size(); i++) {
mStrings[i] = GridViewAppInfoAdapter.lApplication.get(i).toString();
}
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d("toto", "la valeur de app" + GridViewAppInfoAdapter.lApplication);
//setContentView(R.layout.listview);
// setApplication();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, mStrings);
setListAdapter(adapter);
ListView listView = getListView();
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
}
公共类应用程序列表扩展了ListActivity{
私有字符串[]mStrings=（字符串[]）GridViewAppInfoAdapter.laApplication
.toArray（新字符串[GridViewAppInfoAdapter.LaApplication.size（）]）；
