我怎樣才能從視圖完成活動

Question

我有一個有自定義視圖的活動。

我要補充活動結果：

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...> 
    } 
} 

視圖類：

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 - 我有什麼寫在這裏與結果的父活動完成ActView？

我需要事端這樣的：

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

Answer 1

由於Context您使用的是Activitys context, you can cast the view的上下文到活動並調用finish（）上面。

例如：

private void finishFunction() { 
    Activity activity = (Activity)getContext(); 
    activity.finish(); 
} 

也許這是不是從設計的角度來看
