滑动锁屏

Question

使用自定义锁定来锁定和解锁设备，与Start应用程序相同，到目前为止我谷歌并得到了一些问题，但没有运气，即使我发现了一个类似的问题this，但没有希望。< / p>

然而，我尝试使用setOnTouchListener进行滑动，但是它的毛刺并不像Start app那样平滑滑动。

注意：我的代码与Custom Slide to unlock

有些相似

我只是在寻找相同的滑动功能来锁定和解锁设备。

你的建议很明显。

哇，我很高兴，我自己得到了答案。 这是我的难度代码。

public class MainActivity extends Activity implements OnTouchListener {

ImageView left,right;
int leftPosition,rightPosition;
boolean getSize = false;
int width;

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    left = (ImageView)findViewById(R.id.left);
    right = (ImageView)findViewById(R.id.right);

    leftPosition = left.getRight();
    rightPosition = right.getLeft();

    width = getWindowManager().getDefaultDisplay().getWidth();

    left.setOnTouchListener(new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            int eid = event.getAction();
            switch (eid) {
            case MotionEvent.ACTION_DOWN:

                if(!getSize)
                {
                    leftPosition = left.getRight();
                    rightPosition = right.getLeft();
                    getSize =true;
                }
                break;

            case MotionEvent.ACTION_MOVE:

                RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams) left.getLayoutParams();
                int x = (int) event.getRawX();

                if (x>leftPosition) 
                    mParams.width = x;
                left.setLayoutParams(mParams);

            case MotionEvent.ACTION_UP:

    right.setOnTouchListener(new OnTouchListener() {

                right.setLayoutParams(mParams);

            case MotionEvent.ACTION_UP:

                mParam.width = width - rightPosition;
                right.setLayoutParams(mParam);
                break;
            default:
