多線程任務(wù)開發(fā)可以通過以下幾個方式實(shí)現(xiàn)：

1、Handler，如下：

public class MainActivity extends AppCompatActivity {        PRivate MyHandler mHandler = new MyHandler(this);        private TextView mTextView ;        private static class MyHandler extends Handler {            private WeakReference<Context> reference;            public MyHandler(Context context) {                reference = new WeakReference<>(context);            }            @Override            public void handleMessage(Message msg) {                MainActivity activity = (MainActivity) reference.get();                if(activity != null){                    activity.mTextView.setText("");                }            }        }              @Override        protected void onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);            setContentView(R.layout.activity_main);            mTextView = (TextView)findViewById(R.id.textview);            loadData();        }              private void loadData() {            //...request            Message message = Message.obtain();            mHandler.sendMessage(message);        }              @Override        protected void onDestroy() {            super.onDestroy();            mHandler.removeCallbacksAndMessages(null);        }    }

AsyncTask，如下：
public class MainActivity extends AppCompatActivity {        private MyAsyncTask mySyncTask= new MyAsyncTask (this);          private static class MyAsyncTask extends AsyncTask<Void, Void, Void> {        private WeakReference<Context> weakReference;          public MyAsyncTask(Context context) {            weakReference = new WeakReference<>(context);        }          @Override        protected Void doInBackground(Void... params) {            SystemClock.sleep(10000);            return null;        }          @Override        protected void onPostExecute(Void aVoid) {            super.onPostExecute(aVoid);            MainActivity activity = (MainActivity) weakReference.get();            if (activity != null) {                //...            }        }    }                @Override        protected void onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);            setContentView(R.layout.activity_main);        mySyncTask.excute();     }        @Override        protected void onDestroy() {            super.onDestroy();            myAsyncTask.cancle();      }    }請參考：http://blog.csdn.net/q376420785/article/details/8882920點(diǎn)擊打開鏈接
