Heres我的主要活动：

Heres My Main Activity:

public class MainActivity extends ActionBarActivity {

//Navigation Drawer Member Variables
private ListView mDrawerList;
private DrawerLayout mDrawerLayout;
private ArrayAdapter<String> mAdapter;
private ActionBarDrawerToggle mDrawerToggle;
private String mActivityTitle;

            CheckedTextView ctv = (CheckedTextView)view;
            if (ctv.isChecked()){

            }

        }
    });
}



    mDrawerToggle.setDrawerIndicatorEnabled(true);
    mDrawerLayout.setDrawerListener(mDrawerToggle);
}

出现错误说适配器需要文本视图。
任何帮助将非常感谢。感谢

Im getting an error saying that the adapter needs a text view. Any help would be greatly appreciated. Thanks

推荐答案

您得到的错误是，您必须传递一个TextView而不是R.layout.list_item，示例：

The error you are getting is beacuse you have to pass a TextView instead of R.layout.list_item, check the below example:

 mAdapter = new ArrayAdapter<String>(this, R.layout.my_textview, osArray);

要创建 ListView 复选框，请将ChoiceMode设置为CHOICE_MODE_MULTIPLE / p>

To create a ListView with checkboxes set the ChoiceMode to "CHOICE_MODE_MULTIPLE"

    String[] osArray = {"Bluetooth", "Reply to Calls", "Reply to sms", "customise message"};
    ListView listView = (ListView) findViewById(R.id.listView);
    ArrayAdapter arrayAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_multiple_choice, osArray);

    listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    listView.setAdapter(arrayAdapter);
