问题描述
我试图改变样式属性colorControlNormal我的应用程序programmaticaly和运行过程中，但我没有任何结果。
I'm trying to change the style attribute "colorControlNormal" of my app programmaticaly and during runtime, but I didn't have any results.
这属性是将着色汉堡包和放大器的颜色;新的工具栏的ViewGroup回图标。除此之外，我使用的是V7的兼容性库。
This property is the color that will tint the hamburger & back icons of the new Toolbar viewGroup. Beside, I'm using the v7 compatibility library.
我听说，我们不能在运行时改变应用程序的主题，但我正在寻找一个答案，即使它不那么干净的方式。
I heard that we cannot change app theme during runtime, but I'm looking for an answer, even if it's not so clean way.
感谢你了！
编辑：
我想通探微了Gmail是做什么的，我想，当你点击搜索图标，白色汉堡包图标变成灰色的了。
I juste figured that gmail is doing what i want, when you click on the search icon, the white hamburger icon turn into grey back.
等待更多...

我花了一天，打了不同的实现。所以我认为，最好的办法待办事项，它复制粘贴DrawerArrowDrawable从AppCompat V7库。
I spent one day, played with different implementation. So my opinion, the best way todo that it copy paste DrawerArrowDrawable from AppCompat v7 library.

不是你可以用它在你与code主要活动如下
than you can use it in your main activity with code below
DrawerArrowDrawable drawable = new DrawerArrowDrawable(this, this);
ImageView menuButton = (ImageView) findViewById(R.id.arrow);
menuButton.setImageDrawable(drawable);
menuButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
((DrawerLayout)findViewById(R.id.drawer)).openDrawer(Gravity.START);
}
});
当你开始新的片段，你需要在同一个地方再创建一个视图，并添加第二个code到您的片段
when you start new fragment, you need to create one more view on the same place and add second code to your fragment
private DrawerArrowDrawable mArrowDrawable;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mArrowDrawable = new DrawerArrowDrawable(getActivity(), getActivity());
ImageView topButton = (ImageView) view.findViewById(R.id.arrow);
topButton.setImageDrawable(mArrowDrawable);
topButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
closeSearch();
}
});
//run animation from hamburger to arrow
animate(0, 1, null);
....
private void animate(int startValue, int endvalue, Animator.AnimatorListener listener) {
ValueAnimator anim = ValueAnimator.ofFloat(startValue, endvalue);
anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
float slideOffset = (Float) valueAnimator.getAnimatedValue();
mArrowDrawable.setProgress(slideOffset);
}
});
anim.setInterpolator(new DecelerateInterpolator());
anim.setDuration(300);
if (listener != null) {
anim.addListener(listener);
}
anim.start();
}
，使动画从箭头汉堡包处理后退按钮，然后执行code
to make animation from arrow to hamburger handle back button and execute code
animate(1, 0, null);
您还需要等待您的片段，而动画将无法完成，但它的另一个问题。
you also need to wait in your fragment while animation will not finish, but it another questions.
如果您有任何问题，请在注释中。
If you have any questions ask in comments.
