私のアプリでは、タブビューを使用しています。タブの1つに、次のような更新機能を実装します。
private final Runnable r = new Runnable() {
public void run() {
mVar = true;
while (mVar == true){
calculateResult();
//refresh();
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
};
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
handler.removeCallbacks(r);
setContentView(R.layout.result_view);
refresh();
setBackGround();
}
public void refresh() {
new Thread(r).start();
//handler.postDelayed(r, 1000);
}
私はすでにhandler.removeCallbacks(r);
ハンドラーを停止してそれを自分で繰り返すために使用しようとしています。しかし、起動するとシステムがクラッシュします。
これが私のエラーログです:
