## Features

* 支持```OverlaySystem``` 、 ```OverlayActivity``` 和 ```OverlayViewGroup``` 三种模式
* ```OverlaySystem```模式下可在其他APP上显示，自动申请权限
* ```OverlayActivity```模式下只在指定的Activity上显示
* ```OverlayViewGroup```模式下只在指定的ViewGroup上显示
* 可随着手指拖动
* 可双指缩放（可开关）
* 可监听单击和双击事件
* 可指定9个初始位置
* 可指定初始paddings
* 可持有浮动View对象，从而可以动态修改View的内容，并可为浮动View的各个子控件单独设置OnClickListener

## Usage

### Step 1

在project的build.gradle中加入以下语句:  

```
allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}
```

在module的build.gradle中加入以下语句:  

```
dependencies {
    compile 'com.github.hzw1199:FloatingView:1.5.0'
}
```

### Step 2

创建配置并显示

* ```OverlaySystem```模式

onCreate:

```java
FloatingViewConfig config = new FloatingViewConfig.Builder()
        .setPaddingLeft(paddingLeft)
        .setPaddingTop(paddingTop)
        .setPaddingRight(paddingRight)
        .setPaddingBottom(paddingBottom)
        .setGravity(gravity)
        .build();
floatingView = new FloatingView(OverlaySystemActivity.this, R.layout.view_floating, config);
floatingView.showOverlaySystem();
```

onDestroy:

```
if (floatingView != null) {
    floatingView.hide();
}
```

* ```OverlayActivity```模式

onAttachedToWindow:

```java
FloatingViewConfig config = new FloatingViewConfig.Builder()
        .setPaddingLeft(paddingLeft)
        .setPaddingTop(paddingTop)
        .setPaddingRight(paddingRight)
        .setPaddingBottom(paddingBottom)
        .setGravity(gravity)
        .build();
floatingView = new FloatingView(OverlaySystemActivity.this, R.layout.view_floating, config);
floatingView.showOverlayActivity();
```

onDetachedFromWindow:

```
if (floatingView != null) {
    floatingView.hide();
}
```

* ```OverlayViewGroup ```模式

onCreate:

```java
lyViewGroup.post(new Runnable() {
    @Override
    public void run() {
		FloatingViewConfig config = new FloatingViewConfig.Builder()
		        .setPaddingLeft(paddingLeft)
		        .setPaddingTop(paddingTop)
		        .setPaddingRight(paddingRight)
		        .setPaddingBottom(paddingBottom)
		        .setGravity(gravity)
		        .setDisplayWidth(lyViewGroup.getWidth())
		        .setDisplayHeight(lyViewGroup.getHeight())
		        .build();
		floatingView = new FloatingView(OverlaySystemActivity.this, R.layout.view_floating, config);
		floatingView.showOverlayViewGroup(lyViewGroup);
    }
});
```

onDestroy:

```
if (floatingView != null) {
    floatingView.hide();
}
```

```lyViewGroup```是用来放置FloatingView的ViewGroup

### Step 3

点击事件

```java
floatingView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        
    }
});
```

双击事件

```java
floatingView.setOnDoubleClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        
    }
});
```

最大化缩放

```java
floatingView.full();
```

## 持有浮动控件的View对象，可动态修改浮动View的内容
[demo](/app/src/main/java/com/wuadam/demo/AdvancedControlActivity.java)

```java
LayoutInflater mInflater = LayoutInflater.from(AdvancedControlActivity.this);
View floatingView = mInflater.inflate(R.layout.view_advanced_control, null, false);
floatingView = new FloatingView(AdvancedControlActivity.this, floatingView, config);
```

## 为浮动View的各个子控件单独设置OnClickListener
[demo](/app/src/main/java/com/wuadam/demo/AdvancedControlActivity.java)

```java
LayoutInflater mInflater = LayoutInflater.from(AdvancedControlActivity.this);
View floatingView = mInflater.inflate(R.layout.view_advanced_control, null, false);
floatingView = new FloatingView(AdvancedControlActivity.this, floatingView, config);

final View vTop = floatingView.findViewById(R.id.v_top);
final View vMiddle = floatingView.findViewById(R.id.v_middle);
final View vBottom = floatingView.findViewById(R.id.v_bottom);
final TextView tvTime = floatingView.findViewById(R.id.tv_time);


View.OnClickListener onClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (v == vTop) {
            Toast.makeText(AdvancedControlActivity.this, "Top clicked", Toast.LENGTH_SHORT).show();
        } else if (v == vMiddle) {
            Toast.makeText(AdvancedControlActivity.this, "Middle clicked", Toast.LENGTH_SHORT).show();
        } else if (v == vBottom) {
            Toast.makeText(AdvancedControlActivity.this, "Bottom clicked", Toast.LENGTH_SHORT).show();
        }
        tvTime.setText(String.valueOf(System.currentTimeMillis()));
    }
};

vTop.setOnClickListener(onClickListener);
vMiddle.setOnClickListener(onClickListener);
vBottom.setOnClickListener(onClickListener);
```

## Proguard
无需配置混淆规则, `consumerProguardFiles` 已经配置过了
