A framework for directly generating shape through Tags, no need to write shape.xml again（通过标签直接生成shape，无需再写shape.xml）
Add this to your app's build.gradle：
implementation "com.android.support:appcompat-v7:$supportVersion"
implementation 'com.noober.background:core:1.4.0'
Automatic code prompt by Live Templates
1、Calling code before the 'super.onCreate' in BaseActivity
BackgroundLibrary.inject(context);
2、Add the attributes directly in the layout
The following are all custom attributes that are exactly the same as shape and selector.
All attributes of shape are supported. The naming rule is 'tag name'_'tag attribute name':
| name | category |
|---|---|
| bl_shape | rectangle、oval、line、ring(not support yet) |
| bl_solid_color | color |
| bl_corners_radius | dimension |
| bl_corners_bottomLeftRadius | dimension |
| bl_corners_bottomRightRadius | dimension |
| bl_corners_topLeftRadius | dimension |
| bl_corners_topRightRadius | dimension |
| bl_gradient_angle | integer |
| bl_gradient_centerX | float |

| bl_size_height | dimension |
| bl_stroke_width | dimension |
| bl_stroke_color | color |
| bl_stroke_dashWidth | dimension |

detail see :DrawableCreator.Build example:
//设置button圆角背景
Drawable drawable = new DrawableCreator.Builder().setCornersRadius(dip2px(20))
.setGradientAngle(0).setGradientColor(Color.parseColor("#63B8FF"), Color.parseColor("#4F94CD")).build();
btn.setBackground(drawable);
//文字点击变色
tvTest1.setClickable(true);//由于Android源码的原因，必须调用，否则不生效
ColorStateList colors = new DrawableCreator.Builder().setPressedTextColor(Color.RED).setUnPressedTextColor(Color.BLUE).buildTextColor();
tvTest1.setTextColor(colors);
1.stroke+corner+solid
<TextView
android:layout_width="130dp"
android:layout_height="36dp"
android:gravity="center"
android:text="TextView"
android:textColor="#8c6822"
android:textSize="20sp"
app:corners_radius="4dp"
app:solid_color="#E3B666"
app:stroke_color="#8c6822"
app:stroke_width="2dp" />
equals to
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="2dp"/>
<solid android:color="#E3B666"/>
<stroke android:color="#E3B666" android:width="2dp"/>
</shape>
2、gradient
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="2dp"/>
<gradient android:angle="0"
android:startColor="#63B8FF"
android:endColor="#4F94CD"/>
</shape>
equals to
<Button
android:id="@+id/btn"
android:layout_width="130dp"
android:layout_height="36dp"
android:layout_marginTop="5dp"
android:gravity="center"
android:padding="0dp"
android:text="跳转到列表"
android:textColor="#4F94CD"
android:textSize="20sp"
app:corners_radius="2dp"
app:gradient_angle="0"
app:gradient_endColor="#4F94CD"
app:gradient_startColor="#63B8FF" />
the effect of click
the first：
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginTop="5dp"
app:pressed_drawable="@drawable/circle_like_pressed"
app:unPressed_drawable="@drawable/circle_like_normal" />
equals:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/circle_like_pressed" />
<item android:state_pressed="false"
android:drawable="@drawable/circle_like_normal" />
</selector>
the second：
<Button
android:layout_width="300dp"
android:layout_height="50dp"
android:layout_marginTop="5dp"
android:gravity="center"
android:padding="0dp"
android:text="有波纹触摸反馈的按钮"
android:textColor="@android:color/white"
android:textSize="20sp"
app:corners_radius="20dp"
app:pressed_drawable="#71C671"
app:ripple_color="#71C671"
app:ripple_enable="true"
app:stroke_color="#8c6822"
app:stroke_width="2dp"
app:unPressed_drawable="#7CFC00" />
In fact, it is basically the same as shape and selector.
3.Click text discoloration
<Button
android:layout_width="300dp"
android:layout_height="50dp"
android:layout_marginTop="5dp"
android:gravity="center"
android:padding="0dp"
android:text="点击文字变色"
app:pressed_textColor="#919DAF"
app:unPressed_textColor="@android:color/holo_red_dark"/>
4.点击填充边框变色属性
<TextView
android:layout_width="180dp"
android:layout_height="36dp"
android:layout_marginTop="15dp"
android:gravity="center"
android:text="点击边框变色"
android:textColor="@android:color/black"
android:textSize="18dp"
android:textStyle="bold"
android:clickable="true"
app:bl_pressed_solid_color="#FFDEAD"
app:bl_unPressed_solid_color="#E9967A"
app:bl_stroke_width="1dp"
app:bl_pressed_stroke_color="#C6E2FF"
app:bl_unPressed_stroke_color="#98FB98"/>
5.how to use like style
no need to add "app:"
<style name="bg">
<item name="corners_radius">4dp</item>
<item name="solid_color">#E3B666</item>
<item name="stroke_color">#8c6822</item>
<item name="stroke_width">2dp</item>
</style>
<TextView
android:layout_width="130dp"
android:layout_height="36dp"
android:gravity="center"
android:text="TextView"
android:textColor="#8c6822"
android:textSize="20sp"
style="@style/bg"/>
6.set drawableLeft
<Button
android:id="@+id/btn_like"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
app:bl_position="left"
android:background="@null"
android:text="点赞+1"
app:bl_pressed_drawable="@drawable/circle_like_pressed"
app:bl_unPressed_drawable="@drawable/circle_like_normal" />
<Button
android:id="@+id/btn_like2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
app:bl_position="left"
android:background="@null"
android:text="未点赞"
app:bl_selected_textColor="#fbdc4a"
app:bl_unSelected_textColor="@android:color/black"
app:bl_selected_drawable="@drawable/circle_like_pressed"
app:bl_unSelected_drawable="@drawable/circle_like_normal" />
1、selector的相关属性，如果传入的drawable不是颜色的资源，会覆盖掉shape设置的属性
2、在根布局添加
tools:ignore="MissingPrefix"
可以防止报红
3、因为layoutInflater限制了只能有一个factory，如果有其他库已经使用了setFactory方法，比如换肤的库，只需要在其他库调用layoutInflater.setFactory之后调用
BackgroundLibrary.inject2(context);
这样其他的库与本库同样可以生效。
4、selector一个item表示多个属性，暂时无法实现，如下：
<item android:state_pressed="true" android:state_focused="true"
android:drawable="@drawable/button_pressed" />
因为无法用一个属性去表示两种状态，有思路的同学可以告诉我
5、fragment使用无需任何处理，其Activity调用inject即可
6、listView，recyclerView使用也无需任何处理。
如果不生效，只需要
//在调用inflate只需调用一次context，保证adapter创建View时传入的是同一个context即可
BackgroundLibrary.inject(context);
View item = LayoutInflater.from(context).inflate(xxx)
7、自定义View中调用了inflate，同listView一样处理即可
only need to use BLView to replace View(e.g. TextView to BLTextView, EditText to BLEditText) in layout.xml, don't use BLView in the code.
