问题描述

大家好,
              我有从我的主屏幕发射活动widget.And前,有人标注这是一个重复的问题一个问题,请知道我环顾四周,试图在其他类似的questions.Especially这一项中提到的解决方案
    从启动活动部件

我的问题是很简单的,我想从我的主屏幕小部件发起的活动,它不工作。
注:本活动从窗口小部件启动一次(第一次)后,重新安装应用程序的

My problem is simple enough , I want to launch an activity from my home screen widget , and it is not working. Note : The Activity launches from the widget once(for the first time) after a fresh install of the application.

下面是code小部件提供,配置活动和相关的舱单entry.let我知道如果你需要看到code的任意多位。

Here is the code for the widget provide, the configure activity and the relevant manifest entry.let me know if you need to see any more bits of code.

配置活动:

    public class SingleNoteConfigure extends ListActivity  {


private NotesDbAdapter mDbHelper;
int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID;
public static String ACTION_WIDGET_LIST = "ActionReceiverList";
public static String ACTION_WIDGET_NEW = "ActionReceiverNew";



@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //set the result to canceled to allow the user
    //to change their mind mid widget configure
    setResult(RESULT_CANCELED);
    Log.d("MYTAG", "in the onCreate of of the widget configure");

    //set the layout file for the widget configure
    setContentView(R.layout.notes_list_config);

    //using the action bar title for user instruction
    setTitle("Select note to display on the widget");

    // Find the widget id from the intent. 
    Intent intent = getIntent();
    Bundle extras = intent.getExtras();
    if (extras != null) {
        mAppWidgetId = extras.getInt(
                AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
    }
    Log.d("MYTAG", "in the onCreate");
    //stuff to get the database to open
    mDbHelper = new NotesDbAdapter(this);
    mDbHelper.open();

    //call the method that fills the list view
    fillData();

}

 @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);

        Cursor note = mDbHelper.fetchNote(id);
        startManagingCursor(note);
        String title = note.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_TITLE));
        String text = note.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_BODY));



        RemoteViews views = new RemoteViews(this.getPackageName(), R.layout.singlenote_widget);
        AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this); 
        appWidgetManager.updateAppWidget(mAppWidgetId, views);    



        Log.d("MYTAG", "in the onListItemClick....");

        loadData(title, text, id);//here id is the row id of the selection;it is returned by the onListItemSelect 

        Intent resultValue = new Intent();
        resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);            
        setResult(RESULT_OK,resultValue);   
        finish();
 }



 void loadData(String title, String text, Long Id) {

    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this); 
    Log.d("MYTAG", "in the load data....");
    SingleNote.updateWidget(this, appWidgetManager, mAppWidgetId, title, text);
    NotesDbAdapter.updateWidgetId(mAppWidgetId,Id);

}

private void fillData() {
    Cursor notesCursor = mDbHelper.fetchAllNotes();
    startManagingCursor(notesCursor);
    Log.d("MYTAG", "in the fill data  of the widget configure");
    // Create an array to specify the fields we want to display in the list (TITLE and DATE)
    String[] from = new String[]{NotesDbAdapter.KEY_TITLE,NotesDbAdapter.KEY_DATE};


    // and an array of the fields we want to bind those fields to (title and date)
    int[] to = new int[]{R.id.title,R.id.date};


    // Now create a simple cursor adapter and set it to display
    SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.notes_row1, notesCursor, from, to);

    setListAdapter(notes);


}  
}

小部件提供商:

 public class SingleNote extends AppWidgetProvider {

public static String UPDATE_ACTION = "ActionUpdateSinglenoteWidget";

private static NotesDbAdapter mDbHelper;



public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    final int N = appWidgetIds.length;

    // Perform this loop procedure for each App Widget that belongs to this provider
    for (int i=0; i<N; i++) {
        int appWidgetId = appWidgetIds[i];            

        Log.d("MYTAG", "in the onUpdate");

        Intent intent = new Intent(context, Notepadv3.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.singlenote_widget);
        views.setOnClickPendingIntent(R.id.single_note_text, pendingIntent);  

        // Push update for this widget to the home screen

        ComponentName thisWidget = new ComponentName(context, SingleNote.class);
        AppWidgetManager manager = AppWidgetManager.getInstance(context);
        manager.updateAppWidget(thisWidget, views);

    }
}

@Override 
public void onReceive(Context context, Intent intent) { 

    try
    {

    Log.d("MYTAG", "in the onReceive....");
        String action = intent.getAction(); 
        Log.d("MYTAG", "in the onReceive....line 2");
        Bundle extras = intent.getExtras(); 
        Log.d("MYTAG", "in the onReceive....after bundle");
        String title = extras.getString("title");
        Log.d("MYTAG", "in the onReceive....after title");
        String text = extras.getString("body");
        Log.d("MYTAG", "in the onReceive....after text");
        Log.d("MYTAG", "@ the point of int");
        int id = extras.getInt("widget_id");

        Log.d("MYTAG", action+ title + text + id);

        if (action != "rakshak" && action.equals(UPDATE_ACTION)) { 
            final AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); 

            if (id > 0)
            {
                updateWidget(context, appWidgetManager, id ,title ,text);
            }
            else {
                return;

            }
        }
        else { 
            super.onReceive(context, intent); 
        } 

    }
    catch (Exception e)
    {
        Log.e("STACKTRACE_TAG", "STACKTRACE");
        Log.e("STACKTRACE_TAG", Log.getStackTraceString(e));
    }


}

static void updateWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId, String title, String text){

    Log.d("MYTAG", "in the updatewidget method in the siglenote widget....");
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.singlenote_widget);
    views.setTextViewText(R.id.single_note_title, title);
    views.setTextViewText(R.id.single_note_text, text);
    appWidgetManager.updateAppWidget(appWidgetId, views);



}
    }

从Android清单的东西:

The stuff from the android manifest:

  <receiver android:name=".SingleNote" 
                android:label="Y.A.N (single note widget)"
                android:enabled="@bool/is_GB">
        <intent-filter> 
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE"/> 
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
        <meta-data android:name="android.appwidget.provider" 
                   android:resource="@xml/singlenote_widget_provider" />
      </receiver>  

下面是我的2个主要问题:

Here are my 2 main questions:


  1. 我怎么活动启动

  2. ,我如何得到被录音widget的小部件ID?

感谢您抽出时间来阅读这和任何帮助,你可以给。

Thanks for taking the time to read this and for any help that you can give.

推荐答案

我不明白你的活动清单中列出,但你没有粘贴整个文件。确保活动存在那里。

I don't see your activity listed in the manifest, but you didn't paste the whole file. Make sure the activity exists there.

下面是我在我的许多小部件用于启动活动挂起意向工作片段:

Here is a working snippet of the pending intent that I use in many of my widgets to launch activities:

Intent configIntent = new Intent(context, ActivityToBeLaunched.class);
        configIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        // Make the pending intent unique...
        configIntent.setData(Uri.parse(configIntent.toUri(Intent.URI_INTENT_SCHEME)));
        PendingIntent pendIntent = PendingIntent.getActivity(context, 0, configIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        views.setOnClickPendingIntent(R.id.widgetBack, pendIntent);
    }

一件事;我没有看到一个返回意见; 的任何地方。你处​​理其他地方?

One other thing; I don't see a return views; anywhere. Are you handling that elsewhere?
