项目布局常用

多渠道打包

android下直接拷贝

flavorDimensions"versionCode"

aaptOptions.cruncherEnabled =false

aaptOptions.useNewCruncher =false

productFlavors {

kuan {

manifestPlaceholders = [UMENG_CHANNEL_VALUE:"kuan"]

}

xiaomi {

manifestPlaceholders = [UMENG_CHANNEL_VALUE:"xiaomi"]

}

qh360 {

manifestPlaceholders = [UMENG_CHANNEL_VALUE:"qh360"]

}

baidu {

manifestPlaceholders = [UMENG_CHANNEL_VALUE:"baidu"]

}

wandoujia {

manifestPlaceholders = [UMENG_CHANNEL_VALUE:"wandoujia"]

}

}

}

沉浸式

setTranslucentStatus(true);

protected voidsetTranslucentStatus(booleanon) {

if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.KITKAT) {

Window win = getWindow();

WindowManager.LayoutParams winParams = win.getAttributes();

final intbits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;

if(on) {

winParams.flags|= bits;

}else{

winParams.flags&= ~bits;

}

win.setAttributes(winParams);

}

}

侧滑退出

直接粘类 在Activity中实现下列代码

SlidingLayout rootView =newSlidingLayout(this);

rootView.bindActivity(this);

渐进式加载

我用的Xbanner，也可以获得其他空间高

//获得控件的高

ViewTreeObserver vto =xban.getViewTreeObserver();

vto.addOnGlobalLayoutListener(newViewTreeObserver.OnGlobalLayoutListener() {

@Override

public voidonGlobalLayout() {

xban.getViewTreeObserver().removeOnGlobalLayoutListener(this);

banheight= xban.getHeight();

}

});

recycleview的滑动监听事件

rcv.addOnScrollListener(newRecyclerView.OnScrollListener() {

private inttotalDy= 0;

@Override

public voidonScrolled(RecyclerView recyclerView,intdx, intdy //每次滑动的距离) {

初始化int值totalDy 记录每次滑动的高度

totalDy+= dy;

如果滑动高度=0，意思是不画，则文字隐藏，布局透明

if(totalDy<= 0) {

tvChoice.setVisibility(View.GONE);

toptoolbar.setBackgroundColor(Color.argb((int)0,227,29,26));//AGB由相关工具获得，或者美工提供

如果滑动高度>0，则文字显现，布局渐变加载

}else if(totalDy> 0 && totalDy<= banheight) {

tvChoice.setVisibility(View.VISIBLE);

floatscale = (float)totalDy/ banheight;

floatalpha = (255* scale);

// 只是layout背景透明

toptoolbar.setBackgroundColor(Color.argb((int) alpha, 227,29,26));

}else{

文字显现，布局变为需求颜色

tvChoice.setVisibility(View.VISIBLE);

toptoolbar.setBackgroundColor(Color.argb((int)255,227,29,26));

}

}

});

}
