android tips

华为打开logcat

手机: 拨号界面输入：*#*#2846579#*#*
平板: 打开自带计算器输入 ()()2846579()()= 注意,平板要变横屏才能出现括号,竖屏是没有的.

所有界面右下角浮动一个标识

在baseactivity的onCreate方法中,setContentview之后:

       ViewGroup container = (ViewGroup) findViewById(android.R.id.content);
        View view = View.inflate(this,R.layout.label,null);
        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        view.setLayoutParams(params);
        container.addView(view);

viewpager 禁止和允许左右滑动,且可以通过setCurrentItem来切换

网上搜出的大多数都不能用.下面是亲测能用的

public class MyViewPager extends ViewPager {
    private boolean isCanScroll = true;

    public MyViewPager(Context context) {
        super(context);
    }

    public MyViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return this.isCanScroll && super.onTouchEvent(event);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        return this.isCanScroll && super.onInterceptTouchEvent(event);
    }

    public boolean canScroll() {
        return isCanScroll;
    }

    public void setCanScroll(final boolean canScroll) {
        this.isCanScroll = canScroll;
    }
}
