Android 小说阅读护眼模式

实现方案：采用全局dialog 覆盖APP 悬浮在其他APP之上，给dialog设置护眼色值

自定义护眼模式dialog

public class EyeProtectionDialog extends Dialog {    ImageView iv;    public EyeProtectionDialog(@NonNull Context context) {        super(context, R.style.eye_style);        requestWindowFeature(Window.FEATURE_NO_TITLE);        Window window = this.getWindow();        WindowManager.LayoutParams lp = window.getAttributes();        window.getDecorView().setPadding(0, 0, 0, 0);        lp.width = WindowManager.LayoutParams.MATCH_PARENT;        lp.height = WindowManager.LayoutParams.MATCH_PARENT;        lp.flags = WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN                | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE;  //设置不影响下层的触碰        if (Build.VERSION.SDK_INT >= 26) {            lp.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;        } else {            lp.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;        }        window.setAttributes(lp);        window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.eye_layout);        iv = findViewById(R.id.iv_eye);    }    @Override    public void show() {        super.show();        if (iv != null) {            iv.setBackgroundColor(getColor(30));        }    }    /**     *  设置护眼色     * @param blueFilterPercent     * @return     */    public @ColorInt    int getColor(int blueFilterPercent) {        int realFilter = blueFilterPercent;        if (realFilter < 10) {            realFilter = 10;        } else if (realFilter > 80) {            realFilter = 80;        }        int a = (int) (realFilter / 80f * 180);        int r = (int) (200 - (realFilter / 80f) * 190);        int g = (int) (180 - (realFilter / 80f) * 170);        int b = (int) (60 - realFilter / 80f * 60);        return Color.argb(a, r, g, b);    }}

权限以及展示

public void permission() {        if (Build.VERSION.SDK_INT >= 23) {            if (!Settings.canDrawOverlays(getContext())) {                Uri packageURI = Uri.parse("package:" + ReaderApplication.getInstance().getPackageName());                Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, packageURI);                startActivity(intent);            } else {                EyeProtectionDialog eyeProtectionDialog = new EyeProtectionDialog(getContext());                eyeProtectionDialog.show();            }        } else {            EyeProtectionDialog eyeProtectionDialog = new EyeProtectionDialog(getContext());            eyeProtectionDialog.show();        }    }
