我正在基于股票启动器制作我的第一个 android 启动器。我正在尝试将小部件添加到我的主要线性布局中。但这不起作用。它没有比 onActivityResult() 方法更进一步。请帮助我，并提前非常感谢！我的代码：

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();
}

当我按菜单-> 添加小部件时，它会调用 selectWidget() 方法。

当我按下菜单->添加小部件时，所有的 logcat 输出我都选择了一个。

尝试更换您的：

private static final int REQUEST_PICK_APPWIDGET = 9;

和：

private static final int REQUEST_PICK_APPWIDGET = 0;
