我如何从视图中完成活动

Question

我有一个具有自定义视图的活动。

我必须添加活动结果：

    public class ActView extends Activity implements OnClickListener {
<...code...>
@Override
    protected void onCreate(Bundle savedInstanceState) {
    <...code...>
     layout = (LinearLayout) findViewById(R.id.chart_container);
        timelineview = new VDrawTimeLine(this,contentFull);
        timelineview.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
        timelineview.setBackgroundColor(0xffffffff);
        timelineview.setVisibility(View.VISIBLE);

        layout.addView(timelineview);

    <...code...>
    }
}

查看班级：

public class VDrawTimeLine extends View implements OnTouchListener{
<...code...>
public VDrawTimeLine(Context context, ArrayList<_MainData> contentFull) {
        super(context);
        this.con = context;
        this.content = contentFull;
        <...code...>
    }
}
@Override
    public boolean onTouch(View v, MotionEvent event) {
        // TODO Auto-generated method stub
        finishFunction();//I need here finish event this activity result for ActView Activity.
        return true;
    }

finishFunction-我必须在这里写些什么来完成具有父活动结果的ActView？

我需要这样的东西：

Intent intent = new Intent();
    intent.putExtra(dataname, value);
    setResult(RESULT_OK,intent);
    finish();

Answer 1

由于您使用的Context是Activity的Activitys context, you can cast the view上下文，并在其上调用finish（）。

如何在Android Kotlin中从MVVM数据绑定中的View Model类关闭活动。
