android 中如何畫壹條動態的畫壹條直線.(即從A到慢慢運動到B點的軌跡，走過後軌跡是壹條線)

@Override

public void run() {

try {

for(int i = 0 ; i < myPointList.size(); i++)

{

MyPoint myPoint = myPointList1.get(i);

Message message = Message.obtain();

message.what = 2;

message.obj = myPoint;

mHandler.sendMessage(message);

Thread.sleep(100);

}

} catch (Exception e) {

e.printStackTrace();

}

}
