Question

我正在尝试重新加载活动。这是代码：

public class CobaGesture extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ImageButton resetBut = (ImageButton) findViewById(R.id.reset);
    resetBut.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            startActivity(getIntent().setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT)); finish();
        }
    });

当我按下resetBut时，一切都还可以，但我的应用程序有点冻结，当我反复触摸屏幕时，力量关闭我来了。这是logcat：

这是什么意思？怎么解决？如果您有其他方式重新加载活动，请告诉我。

提前感谢。

尝试这样的事情

Intent intent = getIntent();
overridePendingTransition(0, 0);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
finish();

overridePendingTransition(0, 0);
startActivity(intent);

我使用它，它工作正常。

尝试重新加载活动本身时出错
