這篇文章主要介紹了Android實(shí)現(xiàn)個(gè)人資料頁(yè)面頭像背景模糊顯示包括狀態(tài)欄,非常不錯(cuò)，具有參考借鑒價(jià)值，需要的朋友可以參考下

最近要實(shí)現(xiàn)這樣一個(gè)效果，然后拿出來(lái)與大家分享一下主要的幾段代碼，希望大家能夠用到，與人方便自己方便嘛！

首先：

要實(shí)現(xiàn)的是浮動(dòng)狀態(tài)欄效果,通過(guò)在Activity的onCreate方法中調(diào)用這個(gè)方法，然后就可以讓整個(gè)布局浮現(xiàn)在整個(gè)手機(jī)屏幕之下了，這是我覺(jué)著最簡(jiǎn)單的一種方法了。

public static void alphaTask(Activity context) {
  context.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
  if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    Window window = context.getWindow();
    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.TRANSPARENT);
    window.setNavigationBarColor(Color.TRANSPARENT);
  }
}

接下來(lái)：

獲得狀態(tài)欄高度，將actionbar（我這里是自己在布局當(dāng)中寫(xiě)的，然后在代碼中設(shè)置他距離頂部的高度讓他看起來(lái)和我們的bar沒(méi)有什么區(qū)別）的位置改變位于狀態(tài)來(lái)的下方

public static int getStatusBarHight(Context context) {
    /**
     * 獲取狀態(tài)欄高度——方法1
     * */
    int statusBarHeight = -1;
    //獲取status_bar_height資源的ID
    int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
      //根據(jù)資源ID獲取響應(yīng)的尺寸值
      statusBarHeight = context.getResources().getDimensionPixelSize(resourceId);
    }
//    int i = DensityUtil.px2dip(context, statusBarHeight);

    return statusBarHeight;
  }

最后：

實(shí)現(xiàn)背景高斯模糊效果的

public class FastBlurUtils {

  }
}

這里再加一個(gè)上圓形頭像的工具，將圖片轉(zhuǎn)換為圓形，很方便的

/**
 * 轉(zhuǎn)換圖片成圓形
 * @param bitmap 傳入Bitmap對(duì)象
 * @return
 */
public static Bitmap toRoundBitmap(Bitmap bitmap) {
  int width = bitmap.getWidth();
  int height = bitmap.getHeight();
  float roundPx;
  float left, top, right, bottom, dst_left, dst_top, dst_right, dst_bottom;
  if (width <= height) {
    roundPx = width / 2;
    top = 0;
    bottom = width;
    left = 0;
    right = width;
    height = width;
    dst_left = 0;
    dst_top = 0;
    dst_right = width;
    dst_bottom = width;
  } else {
    roundPx = height / 2;
    float clip = (width - height) / 2;
    left = clip;
    right = width - clip;
    top = 0;
    bottom = height;
    width = height;
    dst_left = 0;
    dst_top = 0;
    dst_right = height;
    dst_bottom = height;
  }
  Bitmap output = Bitmap.createBitmap(width,
      height, Bitmap.Config.ARGB_8888);
  Canvas canvas = new Canvas(output);
  final int color = 0xff424242;
  final Paint paint = new Paint();
  final Rect src = new Rect((int)left, (int)top, (int)right, (int)bottom);
  final Rect dst = new Rect((int)dst_left, (int)dst_top, (int)dst_right, (int)dst_bottom);
  final RectF rectF = new RectF(dst);
  paint.setAntiAlias(true);
  canvas.drawARGB(0, 0, 0, 0);
  paint.setColor(color);
  canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
  paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
  canvas.drawBitmap(bitmap, src, dst, paint);
  return output;
}
