在這裏發生的一些奇怪的事情,在item.settext(name);
我得到Cannot resolve method 'settext(java.lang.String)'
。無法解析方法'settext(java.lang.String)'
我正在創建應用程序,其中列表視圖將由數據庫結果動態生成。
佈局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<ListView
android:id="@+id/lvItems"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Study cursors"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
方法
public void bindView(View view, Context context, Cursor cursor) {
ListView item = (ListView) view.findViewById(R.id.lvItems);
String name = cursor.getString(cursor.getColumnIndexOrThrow("name"));
item.settext(name);
}
public View onCreateView(final LayoutInflater inflater, @Nullable final ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dashboard_completed, container, false);
myDB = null;
try {
File dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath());
File file = new File(dir, "database.db");
myDB = SQLiteDatabase.openDatabase(file.toString(), null, SQLiteDatabase.NO_LOCALIZED_COLLATORS|SQLiteDatabase.OPEN_READONLY);
String q = "SELECT * FROM companies ORDER BY name ASC";
Cursor mCursor = myDB.rawQuery(q, null);
// Find ListView to populate
ListView lvItems = (ListView) view.findViewById(R.id.lvItems);
// Setup cursor adapter using cursor from last step
dashboardCursorAdaptor todoAdapter = new dashboardCursorAdaptor(getActivity().getApplicationContext(), mCursor);
// Attach cursor adapter to the ListView
lvItems.setAdapter(todoAdapter);
myDB.close();
} catch (SQLException e) {
e.printStackTrace();
}
return view;
}
謝謝你,你是對的。我需要爲ListView創建2個佈局,爲TextView創建2個佈局。它運作良好。 –
很高興幫助你。 –
