编辑代码以在UI线程上运行

Question

我得到一个错误的线程错误，所以我认为我需要从UI线程运行invalidate。通常是这样的:

public void run() {
                runOnUiThread(new Runnable() {
}});

但是我需要命名这个可运行的从一个方法引用它。我如何将runonuthread纳入其中?

Handler viewHandler = new Handler();
Runnable updateView = new Runnable() {
@Override
public void run() {
    mEmulatorView.invalidate();
    if (statusBool == true) {
        for (int i = 1; i < dataReceived.length() - 1; i++) {
            if (dataReceived.charAt(i) == '>') {
                Log.d(TAG, "found >");
                deviceStatus = 0;
            }
            if (dataReceived.charAt(i) == '#'
                    && dataReceived.charAt(i - 1) != ')') {
                Log.d(TAG, "found #");
                deviceStatus = 1;
            }
            if ((i + 1) <= (dataReceived.length())
                    && dataReceived.charAt(i) == ')'
                    && dataReceived.charAt(i + 1) == '#') {
                Log.d(TAG, "found config )#");
                deviceStatus = 2;
            }
        }
        statusBool = false;
        viewHandler.postDelayed(updateView, 1000);
    }
}
};

调用它:

public void onDataReceived(int id, byte[] data) {
        dataReceived = new String(data);
        ((MyBAIsWrapper) bis).renew(data);
        mSession.write(dataReceived);
        viewHandler.post(updateView);
}

Answer 1

您不需要命名它。如果你想发布自己，你可以使用this关键字:

viewHandler.postDelayed(this, 1000);

mSession.write(dataReceived);导致线程错误。updateView不会引起任何问题。尝试将mSession.write包装为可运行的，并在ui线程上调用它。

Answer 2

让它工作，我只需要在UI线程中运行写行，即使我认为它是?!

public void onDataReceived(int id, byte[] data) {
        dataReceived = new String(data);
        ((MyBAIsWrapper) bis).renew(data);
        runOnUiThread(new Runnable(){
            @Override
            public void run() { 
                mSession.write(dataReceived);       
            }});
        viewHandler.post(updateView);
    }
