ViewFlipper自用 左右滑动切屏、上下滑动调整亮度’

1、xml布局文件 为ViewFlipper添加多个视图

    android:id="@+id/screen_view_flipper"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    android:id="@+id/view1" android:orientation="vertical"
        android:layout_width="match_parent" android:layout_height="match_parent"
        android:background="@color/light_white">
    
    android:id="@+id/view2" android:orientation="vertical"
        android:layout_width="fill_parent" android:layout_height="fill_parent"
        android:background="@color/light_red">
    
    

2、MainActivity 中触摸事件，上下调整屏幕亮度，左右切换view。

 private ViewFlipper mViewFlipper;
 float downX;
 float downY;
 float moveY;
mViewFlipper = (ViewFlipper) findViewById(R.id.screen_view_flipper);
@Override
public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
        downY = event.getY();
        downX = event.getX();
        // 获取当前亮度
        screenBrightness = ViewUtil
        .getScreenBrightness(ScreenLightActivity.this);
        break;
        case MotionEvent.ACTION_MOVE:
        moveY = event.getY();
        float disY = downY - moveY;
        int heightPixels = getResources().getDisplayMetrics().heightPixels / 2;
        float percentLight = disY / heightPixels;
        // 亮度偏移量
        int offsetLight = (int) (percentLight * 100);
        Logger.i("MainActivity", offsetLight+"");
        // 最终亮度
        int endLight = screenBrightness + offsetLight;
        Logger.i("MainActivity", endLight+"");


        if (endLight >= 0 && endLight <= 255) {
        ViewUtil.setBrightness(ScreenLightActivity.this, endLight);
        ViewUtil.saveBrightness(getContentResolver(), endLight);
        }
        break;
        case MotionEvent.ACTION_UP:
        //向右滑动
        if(event.getX()-downX>100){
        mViewFlipper.setInAnimation(this,R.anim.left_in);
        mViewFlipper.setOutAnimation(this,R.anim.right_out);
        mViewFlipper.showNext();
        }
        if (downX-event.getX()>100){
        mViewFlipper.setInAnimation(this,R.anim.right_in);
        mViewFlipper.setOutAnimation(this,R.anim.left_out);
        mViewFlipper.showPrevious();
        }


        break;

default:
        break;
        }

        return super.onTouchEvent(event);
        }
