安卓關閉光標在啓用了StrictMode的測試中

因此，i'v將嚴格模式添加到項目中，現在試圖修復所有這些問題。但我無法弄清楚這一點。我使用ProviderTestCase2 所以這是一個測試方法，我試圖修復：安卓關閉光標在啓用了StrictMode的測試中

public void testTaskInsertAndUpdateAndQuerySingleItem() { 
    final ContentValues contentValues = defaultTaskContentValues(); 

    final Uri uri = mMockContentResolver.insert(TaskTemplatesContract.TaskTemplateColumns.CONTENT_URI, contentValues); 
    assertNotNull(uri); 

    Cursor cursor = mMockContentResolver.query(TaskTemplatesContract.TaskTemplateColumns.CONTENT_URI, null, "ID=?", new String[]{TASK_ID}, null); 
    try { 
     assertEquals(1, cursor.getCount()); 
     contentValues.put(TaskTemplatesContract.TaskTemplateColumns.NAME, "View contact data."); 
     int rowsUpdated = mMockContentResolver.update(TaskTemplatesContract.TaskTemplateColumns.CONTENT_URI, contentValues, "NAME=?", new String[]{TASK_NAME}); 
     assertEquals(1, rowsUpdated); 
    } finally { 
     cursor.close(); 
    } 

    Cursor c = mMockContentResolver.query(uri, null, null, null, null); 
    try { 
     assertTrue(c.moveToNext()); 
     assertEqualsRowColumnStringValue(c, TaskTemplatesContract.TaskTemplateColumns.NAME, "View contact data."); 
    } finally { 
     c.close(); 
    } 
}

JobTemplatesProvider方法：

@Override 
public Cursor query(Uri uri, String[] projection, String where, String[] whereArgs, String sortOrder) { 
    SQLiteQueryBuilder qb = new SQLiteQueryBuilder(); 
    String tableName; 
    switch (sUriMatcher.match(uri)) { 
     case JOB_TEMPLATE_ID: 
      qb.setProjectionMap(sJobTemplatesProjectionMap); 
      qb.appendWhere(JobTemplatesContract.JobTemplateColumns._ID + "=" + uri.getPathSegments().get(1)); 
      tableName = JOB_TEMPLATES_TABLE_NAME; 
      break; 
     case TASK_TEMPLATES: 
      qb.setProjectionMap(sTaskTemplatesProjectionMap); 
      tableName = TASK_TEMPLATES_TABLE_NAME; 
      break; 
     default: 
      throw new IllegalArgumentException(UNKNOWN_URI + uri); 
    } 
    qb.setTables(tableName); 
    SQLiteDatabase db = mDatabaseHelper.getReadableDatabase(); 
    Cursor c = qb.query(db, projection, where, whereArgs, null, null, sortOrder); 

    c.setNotificationUri(getContext().getContentResolver(), uri); 
    return c; 
    }

，但我仍然得到同樣的問題，關於明確調用close的（）方法Cursor：

任何線索都會對您有所幫助！乾杯。

請出示你的'JobTemplatesProvider.query'方法 – nikis

@nikis查詢代碼添加 – Kamil

能否請您也表明你的'JobTemplatesProviderTestCase.testTaskInsertAndUpdateAndQuerySingleItem'方法？我認爲這個問題的發生是因爲當你摧毀你的活動時你不關閉db.close。 – nikis

這裏我找到了一個解決方案。嚴格模式一般如下：

StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork().penaltyLog().build()); 
    StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectLeakedSqlLiteObjects().detectLeakedClosableObjects().penaltyLog().penaltyDeath().build());

只需從VmPolicy中刪除detectLeakedSqlLiteObjects（）。所以它應該是

StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork().penaltyLog().build()); 
    StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectLeakedClosableObjects().penaltyLog().penaltyDeath().build());
