    @Override
   public void onItemClick(AdapterView<?> parent, final View view, final int position, long id) {

    showDialog(position);

    }
});

Answer 1

您可以使用此不允许多次快速点击的代码代替您的 onclicklistener。

public abstract class SingleClickListener implements View.OnClickListener {
    private static final long THRESHOLD_MILLIS = 500L;
    private long lastClickMillis;

    @Override
    public void onClick(View v) {
        long now = SystemClock.elapsedRealtime();
        if (now - lastClickMillis > THRESHOLD_MILLIS) {
            onClicked(v);
            lastClickMillis = 0;
        } else {
            lastClickMillis = now;
        }
    }

    public abstract void onClicked(View v);
}

而不是普通的 onclicklistener 使用这个

 stage1_nxt.setOnClickListener(new SingleClickListener() {
