Support three modes: OverlaySystem 、 OverlayActivity and OverlayViewGroup
OverlaySystem: Display FloatingView above other apps
OverlayActivity: Display FloatingView above certain Activity
OverlayViewGroup: Display FloatingView above certain ViewGroup
Move FloatingView with finger
Scale FloatingView with two fingers (can be disabled)
Listen to click and double-click events
Define 9 initial position for FloatingView
Define initial paddings for FloatingView
Hold FloatingView object, so that you can change the content of FloatingView dynamically, and set OnClickListener for each child view of FloatingView

Usage

Step 1

Add it in your build.gradle at the end of repositories:

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

Add the dependency in the form:

dependencies {
    compile 'com.github.hzw1199:FloatingView:1.7.0'
}

Step 2

Configure and display

OverlaySystem mode

AndroidManifest.xml:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" ></uses-permission>

onCreate:

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 mode

onAttachedToWindow:

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 mode

onCreate:

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 is the ViewGroup to display FloatingView above

Step 3

Click event

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

Double-click event

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

Maximize zoom

floatingView.full();

Hold the Floating View object, to change the content logically

demo

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

Set OnClickListener for subviews of Floating View

demo

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

No need to add more proguard rules, consumerProguardFiles has already handled library proguard rules.
