Android發射器小部件問題

Question

我正在製作基於股票啓動器的第一個android啓動器。我正在嘗試將小部件添加到我的主要線性佈局中。但那不行。它沒有比onActivityResult（）方法更進一步。請幫助我，並提前感謝！我的代碼：

private static final int REQUEST_CREATE_SHORTCUT = 1; 
private static final int REQUEST_CREATE_LIVE_FOLDER = 4; 
private static final int REQUEST_CREATE_APPWIDGET = 5; 
private static final int REQUEST_PICK_APPLICATION = 6; 
private static final int REQUEST_PICK_SHORTCUT = 7; 
private static final int REQUEST_PICK_LIVE_FOLDER = 8; 
private static final int REQUEST_PICK_APPWIDGET = 9; 
private static final int REQUEST_PICK_ANYCUT=10; 
private static final int REQUEST_SHOW_APP_LIST = 11; 
private static final int REQUEST_EDIT_SHIRTCUT = 12; 

    mAppWidgetManager = AppWidgetManager.getInstance(this); 
    mAppWidgetHost = new AppWidgetHost(this, R.id.linearLayout); 

//Add widgets 

void selectWidget() { 
    int appWidgetId = this.mAppWidgetHost.allocateAppWidgetId(); 
    Intent pickIntent = new Intent(AppWidgetManager.ACTION_APPWIDGET_PICK); 
    pickIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); 
    addEmptyData(pickIntent); 
    Log.d("addWidgetProcedure", "Starting activity to pick widget"); 
    startActivityForResult(pickIntent, REQUEST_PICK_APPWIDGET); 
} 

void addEmptyData(Intent pickIntent) { 
    ArrayList<AppWidgetProviderInfo> customInfo = 
     new ArrayList<AppWidgetProviderInfo>(); 
    pickIntent.putParcelableArrayListExtra(
     AppWidgetManager.EXTRA_CUSTOM_INFO, customInfo); 
    ArrayList<Bundle> customExtras = new ArrayList<Bundle>(); 
    pickIntent.putParcelableArrayListExtra(
     AppWidgetManager.EXTRA_CUSTOM_EXTRAS, customExtras); 
    Log.d("addWidgetProcedure", "AddEmptyData"); 
}; 

@Override 
protected void onActivityResult(int requestCode, int resultCode, 
           Intent data) { 
    Log.d("addWidgetProcedure", "inside onActivityResult"); 
    if (resultCode == RESULT_OK) { 
     Log.d("addWidgetProcedure", "RESULT_OK"); 
     if (requestCode == REQUEST_PICK_APPWIDGET) { 
      Log.d("addWidgetProcedure", "calling configureWidget(data)"); 
      configureWidget(data); 
     } 
     else if (requestCode == REQUEST_CREATE_APPWIDGET) { 
      Log.d("addWidgetProcedure", "calling createWidget(data)"); 
      createWidget(data); 
     } 
    } 
    else if (resultCode == RESULT_CANCELED && data != null) { 
     Log.d("addWidgetProcedure", "RESULT_CANCELED"); 
     int appWidgetId = 
      data.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1); 
     if (appWidgetId != -1) { 
      mAppWidgetHost.deleteAppWidgetId(appWidgetId); 
     } 
    } 
} 

private void configureWidget(Intent data) { 
    Bundle extras = data.getExtras(); 
    int appWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, -1); 
    AppWidgetProviderInfo appWidgetInfo = 
     mAppWidgetManager.getAppWidgetInfo(appWidgetId); 
    if (appWidgetInfo.configure != null) { 
     Intent intent = 
      new Intent(AppWidgetManager.ACTION_APPWIDGET_CONFIGURE); 
     intent.setComponent(appWidgetInfo.configure); 
     intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); 
     startActivityForResult(intent, REQUEST_CREATE_APPWIDGET); 
    } else { 
     createWidget(data); 
    } 
} 

public void createWidget(Intent data) { 
    Bundle extras = data.getExtras(); 
    int appWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, -1); 
    AppWidgetProviderInfo appWidgetInfo = 
     mAppWidgetManager.getAppWidgetInfo(appWidgetId); 
    AppWidgetHostView hostView = 
     mAppWidgetHost.createView(this, appWidgetId, appWidgetInfo); 
    hostView.setAppWidget(appWidgetId, appWidgetInfo); 
    linearLayout.addView(hostView); 
    Toast.makeText(getApplicationContext(), "Adding widget", 15).show(); 
} 

當我按菜單 - >添加小部件時，它調用了selectWidget（）方法。

當我按菜單 - >添加小部件到我選擇了一個時，所有的logcat輸出。

Answer 1

嘗試更換您：

private static final int REQUEST_PICK_APPWIDGET = 9; 

有了：

private static final int REQUEST_PICK_APPWIDGET = 0;
