私が見る限り、問題は ConcurrentModificationException にあると思います。調査しましたが、確かに理解できません:/。

これは、チャートが再描画されている私の Java コードの一部です。

    //onResume() se llama al resumir la Activity y tambien al crearse la Activity

        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        myThread = null;    //pongo el Thread como null para no provocar errores

    @Override

        while(Running){

            int[] factor = {0, 2, 4, 6}; 

            if(DEBUG) Log.i(TAG, "run() -> LogicAnalizerView");

            data = USBMulti.getLogicAnalizerData();
            for(int n = 0; n < 4; ++n){
                if(bitTest(data,n)) factor[n] += 1;
            }

            if(DEBUG) Log.i(TAG, "run() -> LogicAnalizerView - input.add(" + time + "),factor[n]");

わかりました私は解決策を見つけました。問題は、UI スレッドではないスレッドで UI を更新しているため、以下のようにハンドラーを使用し、UI を変更するコードをハンドラーに配置する必要があることです。run() メソッドからハンドラーを呼び出します。

uiCallback.sendEmptyMessage(0);

ハンドラーは uiCallback と呼ばれ、次の方法でハンドラーを定義します。

private Handler uiCallback = new Handler () {
    public void handleMessage (Message msg) {
        if (DEBUG) Log.i(TAG, "run() -> Handler");
        int[] factor = {0, 2, 4, 6};

        data = USBMulti.getLogicAnalizerData();
        for(int n = 0; n < 4; ++n) {
            if(bitTest(data,n)) factor[n] += 1;
        }

        input1.add(time,factor[0]);
        input2.add(time,factor[1]);
        input3.add(time,factor[2]);
        input4.add(time,factor[3]);

        if (DEBUG) Log.i(TAG, "run() -> LogicAnalizerView - mView.repaint()");
        if (mView != null) {
            mView.repaint(); // Redibujo el grafico
        }
        time += 0.1;
    }
};

だから私はUIスレッドでチャートを再描画し、それは完全に機能します:)。

ありがとうございます ：）

achartengineが同じデータセットを反復処理しているの.addと同時に、データセットを呼び出しているように見えます。

再描画がどのように機能するかは 100% わかりませんが、別のスレッドで起動する場合は、変更中にデータセットを読み取らないように同期する方法が必要になる場合があります。

正確な方法はわかりませんが、これが正しい方向に向けられることを願っています。
