android小部件ArrayAdapter上的NullPointerException

---

可能

c.getString

返回空值您是否创建了

活动\u customview

布局？它是否也有

R.id.tv

视图？是

private void fillArrayAdapter() {
        Cursor c = db.rawQuery("SELECT * FROM quotes", null);
        int count = c.getCount();
        int column = c.getColumnCount();
        Log.d("countcl", column + "");
        totalRec = new String[count * column];
        Log.d("counttot", totalRec + "");
        int i = 0;
        c.moveToFirst();
        while (!c.isAfterLast()) {
            totalRec[i++] = c.getString(c.getColumnIndex("qoutemsg"));
            c.moveToNext();
        }

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                getBaseContext(), R.layout.activity_customview, R.id.tv,
                totalRec);
        lv1 = (ListView) findViewById(R.id.listViewQuotes);
        lv1.setAdapter(adapter);

    }
