小编Mou*_*ssi的帖子

更新: 了解我的问题,这是我需要实现的:将图标从App抽屉拖动到主屏幕(如果可能的话,不是在gridview中),如图片中所示,

旧(这只是为了了解这是如何工作的):

我正在尝试将一个可点击的图标从一个拖动ListView到一个customView没有容器(Listview or Gridview...)的同一个Activity或另一个,这里有一张图片供您了解:

但是当我把图标放在右边区域时我看不到对象,在日志中我看到:I/ViewRootImpl? Reporting drop result: true

我的代码:

class MyDragListener implements View.OnDragListener {
    @Override
    public boolean onDrag(View v, DragEvent event) {
        int action = event.getAction();
        switch (event.getAction()) {
            ...
            case DragEvent.ACTION_DROP:
                LinearLayoutAbsListView itemo = (LinearLayoutAbsListView)findViewById(R.id.paneko);
                View child = getLayoutInflater().inflate(R.layout.list_item, null);
                itemo.addView(child);
                break;
            case DragEvent.ACTION_DRAG_ENDED:
             default:
                break;
        }
        return true;
    }
}

我的XML文件:

...
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="2"
    android:background="@android:color/background_dark"
    android:orientation="horizontal" >

    <com.moapps.elfassimounir.simple.LinearLayoutAbsListView
        android:id="@+id/paneuj"
        android:background="@android:color/background_light"
        android:orientation="vertical"
        > …

我有这个错误setOnItemSelectedListener:

AdapterView类型中的方法setOnItemSelectedListener(AdapterView.OnItemSelectedListener)不适用于参数(FragmentMain)"

片段类:

public class FragmentMain extends Fragment  {

private Spinner countriesSpinner;
private Activity rootView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState){
     View rootView =inflater.inflate(R.layout.activity_main, container, false);
     return rootView;
}
@Override
public void onStart() {
    super.onStart();

    addItemsOnSpinner();
}
public void addItemsOnSpinner() {

    countriesSpinner = (Spinner) rootView.findViewById(R.id.team_list_spinner);
    countriesSpinner.setOnItemSelectedListener(new  CustomOnItemSelectedListener ()) ;

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getActivity(),
            R.array.team_list, android.R.layout.simple_spinner_item);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    countriesSpinner.setAdapter(adapter);

    countriesSpinner.setOnItemSelectedListener(this);

    }

public class CustomOnItemSelectedListener extends Activity implements
OnItemSelectedListener {

    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int pos, …

生成的"app-release.apk"不能用于我的设计,但"app-debug.apk"工作正常,

更新:

在转到我的应用程序的上一版本之后:

在我的MainActivity我有这个字符串:

public class MainActivity extends ActionBarActivity {

 @Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     final String PREFS_NAME = "MyPrefsFile";

     SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);

     if (settings.getBoolean("my_first_time", true)) {
         //the app is being launched for first time, do something

         TeamModel pm;
         DBHelper db;

         String teamNames1= "Los Angeles Lakers";
         String teamOpponent1= "Golden State Warriors";
         String teamDate1= "2015-03-16 22:30";

         String teamNames2= "Atlanta Hawks";
         String teamOpponent2= "Sacramento Kings";
         String teamDate2= "2015-03-16 20:00";

         .
         .

         String teamNames348= "Charlotte Hornets"; …
