getContext()); MenuWidth=ScreenWidth/4; HalfMenuWidth=MenuWidth/2; left.getLayoutParams...().width=MenuWidth; centre.getLayoutParams().width=ScreenWidth; right.getLayoutParams...我们首先拿到左菜单，内容，右菜单所对用的view,即left,centre,right这三个View,然后获取屏幕的宽度，动态设定菜单的宽度为屏幕宽度的四分之一，而内容的宽度就是整个屏幕的宽度，即 left.getLayoutParams...().width=MenuWidth; centre.getLayoutParams().width=ScreenWidth; right.getLayoutParams().width=MenuWidth
获取ViewGroup.LayoutParams getLayoutParams()方法可以获取ViewGroup.LayoutParams对象。...super(context, attrs, defStyle); setupView(context); } private void setupView(Context context) { if (getLayoutParams...findViewById(R.id.inner_layout); FrameLayout.LayoutParams par = (FrameLayout.LayoutParams) innerLayout.getLayoutParams...findViewById(R.id.inner_layout); LinearLayout.LayoutParams par = (LinearLayout.LayoutParams) innerLayout.getLayoutParams

outMetrics.heightPixels; 假设我当前是在A页面，我要分享出去的B图片和A页面只需要隐藏分享按钮，接下来提供第二种方法，这种方法的做法是： Bitmap b = Bitmap.createBitmap( v.getLayoutParams...().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); v.layout...* 创建分享Bitmap */ private Bitmap createBitmap() { //自定义ViewGroup，一定要手动调用测量，布局的方法 measure(getLayoutParams...().width, getLayoutParams().height); layout(0, 0, getMeasuredWidth(), getMeasuredHeight());

LinearLayout.LayoutParams 代码如下： LinearLayout.LayoutParams layoutParams=(LinearLayout.LayoutParams)getLayoutParams...RelativeLayout.LayoutParams layoutParams=(RelativeLayout.LayoutParams)getLayoutParams(); layoutParams.leftMargin...ViewGroup.MarginLayoutParams来实现： ViewGroup.MarginLayoutParams layoutParams=(ViewGroup.MarginLayoutParams)getLayoutParams
ScreenUtil(this).getAppWidth(); float width = new ScreenUtil(this).getAppHeight(); mRlVv.getLayoutParams...().height = (int) width; mRlVv.getLayoutParams().width = (int) height; } else { /...ScreenUtil(this).getAppWidth(); float height = DisplayUtil.dp2px(this, 200.f); mRlVv.getLayoutParams...().height = (int) height; mRlVv.getLayoutParams().width = (int) width; } } 里面有几个uitl, 都是常见的封装
private final TextView name,selectedBar; public VH(View v) { super(v); v.getLayoutParams...().width = getActivity().getWindowManager().getDefaultDisplay().getWidth() / 4 + 30; v.getLayoutParams...().height = v.getLayoutParams().width / 2 ; name = (TextView) v.findViewById(R.id.main_goods_species_name

canvas.translate(-tranX, 0); super.onDraw(canvas); } 我们可以看到，文字也居中了： [1240] 最后再说一下收缩效果的实现方式 主要也是通过getLayoutParams...().width和getLayoutParams().height来改变布局的尺寸，在开始收缩时先将文本设置为空drawablePadding字符0，设为，然后再开始收缩动画，具体的方式可以自行尝试。...// b = getRootViewSize() // k = getRootViewSize() - getLoadingSize getLayoutParams...mRootViewSizeSaved[0]) * (float) animation.getAnimatedValue() + mRootViewSizeSaved[0]); getLayoutParams
super.onMeasure(widthMeasureSpec, heightMeasureSpec); LayoutParams params = (LayoutParams) getChildAt(1).getLayoutParams...并且向下滑动时，则不断的放大图片（通过改变ImageView）的高度 LayoutParams layoutParams = (LayoutParams) getChildAt(0) .getLayoutParams...(1).getTop() imageHeight) { LayoutParams layoutParams = (LayoutParams) getChildAt(0) .getLayoutParams...) animation.getAnimatedValue(); LayoutParams layoutParams = (LayoutParams) getChildAt(0) .getLayoutParams

R.drawable.button_selector); setGravity(Gravity.CENTER); setClickable(true); } } 在将布局添加到布局后,我从代码中设置了Button的宽度和高度： button.getLayoutParams...().width = myWidth; button.getLayoutParams().height = myHeight; button_selector.xml： android:drawable
(Integer) animator.getAnimatedValue(); // 根据比例更改目标view的宽度 view.getLayoutParams...最后，对象实际的宽度值为view.getLayoutParams().width。...this.maxWidth = maxWidth; } public int getWidth() { return target.getLayoutParams...public void setWidth(int widthValue) { //widthValue的值从100到20变化 target.getLayoutParams...().width; } public void setWidth(int widthValue) { target.getLayoutParams().
