修改状态栏与导航栏颜色

1.修改状态栏

可进行自定义

public class StatusBarView extends View {
    private Context context;
    public StatusBarView(Context context) {
        this(context,null);
    }

    public StatusBarView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context=context;

    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(ScreenUtils.getStatusBarHeight(context), MeasureSpec.EXACTLY));
    }
}

<com.cy.translucentparent.StatusBarView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#33000000" />

2.工具类

a.分辨率转换工具类

public class ScreenUtils {
      //获得状态栏高度
    public static int getStatusBarHeight(Context context) {
        Resources resources = context.getResources();
        int resourceId = resources.getIdentifier("status_bar_height", "dimen", "android");
        return resources.getDimensionPixelSize(resourceId);
    }
   //获得导航栏高度
    public static int getNavigationBarHeight(Context context) {
        Resources resources = context.getResources();
        int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
        return resources.getDimensionPixelSize(resourceId);
    }
   //获得屏幕宽度
    public static int getScreenWidth(Context context) {
        DisplayMetrics displayMetrics = new DisplayMetrics();
        WindowManager wm = (WindowManager) context
                .getSystemService(Context.WINDOW_SERVICE);

        wm.getDefaultDisplay().getMetrics(displayMetrics);
        return displayMetrics.widthPixels;
    }
  //获得屏幕高度
    public static int getScreenHeight(Context context) {
        DisplayMetrics displayMetrics = new DisplayMetrics();
        WindowManager wm = (WindowManager) context
                .getSystemService(Context.WINDOW_SERVICE);

        wm.getDefaultDisplay().getMetrics(displayMetrics);
        return displayMetrics.heightPixels;
    }

    /**
     * 将px值转换为dip或dp值，保证尺寸大小不变
     *
     * @param pxValue
     * @param scale   （DisplayMetrics类中属性density）
     * @return
     */
    public static int px2dp(Context context, float pxValue) {
        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (pxValue / scale + 0.5f);
    }

    /**
     * 将dip或dp值转换为px值，保证尺寸大小不变
     *
     * @param dipValue
     * @param scale    （DisplayMetrics类中属性density）
     * @return
     */
    public static int dpInt2px(Context context, int dipValue) {
        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (dipValue * scale + 0.5f);
    }

    public static int dp2px(Context context, int dimen_resID) {
        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (context.getResources().getDimension(dimen_resID) * scale + 0.5f);
    }

    /**
     * 将px值转换为sp值，保证文字大小不变
     *
     * @param pxValue
     * @param fontScale （DisplayMetrics类中属性scaledDensity）
     * @return
     */
    public static int px2sp(Context context, float pxValue) {
        final float fontScale = context.getResources().getDisplayMetrics().scaledDensity;
        return (int) (pxValue / fontScale + 0.5f);
    }

    /**

     *
     * @param spValue
     * @param fontScale （DisplayMetrics类中属性scaledDensity）
     * @return
     */
    public static int sp2px(Context context, float spValue) {
        final float fontScale = context.getResources().getDisplayMetrics().scaledDensity;
        return (int) (spValue * fontScale + 0.5f);
    }

    /**
     * 计算指定的 View 在屏幕中的坐标。
     */
    public static RectF calcViewScreenLocation(View view) {
        int[] location = new int[2];
        // 获取控件在屏幕中的位置，返回的数组分别为控件左顶点的 x、y 的值
        view.getLocationOnScreen(location);
        return new RectF(location[0], location[1], location[0] + view.getWidth(),
                location[1] + view.getHeight());
    }

    /**
     * 判断触摸点是否在控件内
     */
    public static boolean isInViewRange(View view, MotionEvent event) {

        // MotionEvent event;
        // event.getX(); 获取相对于控件自身左上角的 x 坐标值
        // event.getY(); 获取相对于控件自身左上角的 y 坐标值
        float x = event.getRawX(); // 获取相对于屏幕左上角的 x 坐标值
        float y = event.getRawY(); // 获取相对于屏幕左上角的 y 坐标值

        // View view;
        RectF rect = calcViewScreenLocation(view);
        return rect.contains(x, y);
    }
}

b.修改状态栏颜色与导航栏颜色的工具类

public class StatusNavUtils {


    /**
     * 状态栏透明去阴影（5.0以上）
     *
     * @param activity
     * @param color
     */
    public static void setStatusBarColor(Activity activity, int color) {
        Window window = activity.getWindow();

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(color);
            return;
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

        }

    }

    /**
     * 导航栏全透明去阴影（5.0以上）
     *
     * @param activity
     * @param color
     */

    public static void setNavigationBarColor(Activity activity, int color) {
        Window window = activity.getWindow();

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setNavigationBarColor(color);
            return;
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

        }
    }

    /**
     * 状态栏、导航栏全透明去阴影（5.0以上）
     *
     * @param activity
     * @param color_status
     * @param color_nav
     */
    public static void setStatusNavBarColor(Activity activity, int color_status, int color_nav) {
        Window window = activity.getWindow();

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

            window.setStatusBarColor(color_status);

            window.setNavigationBarColor(color_nav);
            return;
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

        }
    }
}

c:用法

StatusNavUtils.setStatusBarColor(this,0x00000000);

StatusNavUtils.setNavigationBarColor(this,0x33000000);
