集成 Integrate

  • 将library导入到工程中 // import library as a model to your project

  • 或者将library中的FloatBackground.java，FloatObject.java复制到你的项目中去 // Or copy FloatBackground.java ,FloatObject.java from library to your project

使用 Usage

FloatBackground

FloatBackground继承自FrameLayout，在使用时添加FloatBackground 到你的布局文件中，并作为最底层的ViewGroup，这样在其之上的视图都可以以FloatBackground为一层背景显示浮动动画。

FloatBackground is inhert from FrameLayout, add FloatBackground to your layout XML file, and set it in the lowest layer in your layout.

<com.dean.library.FloatBackground
        android:id="@+id/float_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_gravity="center"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <Button
                android:id="@+id/start"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:text="Start" />

            <Button
                android:id="@+id/end"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:text="End" />
        </LinearLayout>
    </com.dean.library.FloatBackground>

FloatObject

漂浮对象，初始化漂浮对象，继承FloatObject，并重写drawFloatObject方法。 FloatObject is a base class to create "Floating object" on FloatBackground. need to overwrite drawFloatObject method.

public class FloatText extends FloatObject {
    String text;

    public FloatText(float posX, float posY, String text) {
        super(posX, posY);
        this.text = text;
        setAlpha(88);
        setColor(Color.WHITE);
    }

    @Override
    public void drawFloatObject(Canvas canvas, float x, float y, Paint paint) {
        paint.setTextSize(65);
        canvas.drawText(text, x, y, paint);
    }
}

将FloatObject添加到FloatBackground/add FloatObject into FloatBackground

FloatBackground floatBackground = (FloatBackground) this.findViewById(R.id.float_view);
floatBackground.addFloatView(new FloatText( 0.3f, 0.6f, "E"));

startFloat

播放悬浮动画，start floating animation

floatBackground.startFloat();

endFloat

结束悬浮动画，end floating anmiation

floatBackground.endFloat();
