android 线程里面的循环不执行

Question

new Thread(new Runnable() {
@Override
public void run() {
person.name = "QQQ";
person.age = 999;
ContentValues cv = new ContentValues();
cv.put("name", person.name);
cv.put("age", person.age);
for (int i =0;i<10;i++){
db.insert("person", null, cv);
}

        }
    }).start();

            就创建了一个列表，想在线程中循环插入信息     请问怎么解决

Answer 1

final SQLiteDatabase db = openOrCreateDatabase("test.db", Context.MODE_PRIVATE, null);
db.execSQL("DROP TABLE IF EXISTS person");
db.execSQL("CREATE TABLE person (_id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR, age SMALLINT)");
new Thread(new Runnable() {
@Override
public void run() {
ContentValues cv1 = new ContentValues();
cv1.put("name", "张");
cv1.put("age", 18);
for (int i =0;i<10;i++){ db.insert("person", null, cv1); db.insert("person", null, cv1); }

            Cursor c= db.rawQuery("SELECT * FROM person", null);
            while (c.moveToNext()) {
                    int _id = c.getInt(c.getColumnIndex("_id"));
                    String name = c.getString(c.getColumnIndex("name"));
                    int age = c.getInt(c.getColumnIndex("age"));
                    Log.i("db", "_id=>" + _id + ", name=>" + name + ", age=>" + age);
            }
    }

}).start();
你这样试试
