Java代碼
// 詳見StrictMode文檔
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork()
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());
另一種是啓動線程執行下載任務：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 啓動線程執行下載任務
new Thread(downloadRun).start();
}
/**
* 下載線程
*/
Runnable downloadRun = new Runnable(){
@Override
public void run() {
updateListView();
}
};
new Thread(){
@Override
public void run(){
//你要執行的方法
//執行完畢後給handler發送一個空消息
handler.sendEmptyMessage(0);
}
}.start();
//定義Handler對象
private Handler handler =new Handler(){
@Override
//當有消息發送出來的時候就執行Handler的這個方法
public void handleMessage(Message msg){
super.handleMessage(msg);
//處理UI
}
};
方法二：
public class IniteAppDataInfoTask extends AsyncTask<Void, Void, String> {
@Override
protected String doInBackground(Void... arg0) {
// TODO Auto-generated method stub
IniteAppDataInfo();//請求http
return "SUCCESS";
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new IniteAppDataInfoTask().execute();
}
