这个库就是你需要的

在活动中

    blurView = (BlurView) findViewById(R.id.blurView);

    final View decorView = getWindow().getDecorView();
    final View rootView = decorView.findViewById(android.R.id.content);
    final Drawable windowBackground = decorView.getBackground();

    blurView.setupWith(rootView)
            .windowBackground(windowBackground)
            .blurAlgorithm(new RenderScriptBlur(this, true)) //Preferable algorithm, needs RenderScript support mode enabled
            .blurRadius(10);

    renderscriptTargetApi 23
    renderscriptSupportModeEnabled true

    blurView = (BlurView) findViewById(R.id.blurView);

    final View decorView = getWindow().getDecorView();
    final View rootView = decorView.findViewById(android.R.id.content);
    final Drawable windowBackground = decorView.getBackground();

    blurView.setupWith(rootView)
            .windowBackground(windowBackground)
            .blurAlgorithm(new RenderScriptBlur(this, true)) //Preferable algorithm, needs RenderScript support mode enabled
