Android(安卓)获取屏幕尺寸实例代码

Android 获取屏幕尺寸实例代码

实现代码：

/**  *   *   * 使Android程序支持了多种分辨率  */ int mWidthScreen,mHeightScreen; Display display = getWindowManager().getDefaultDisplay(); mWidthScreen = display.getWidth(); mHeightScreen = display.getHeight(); LogUtils.e("Width：" + display.getWidth()); LogUtils.e("Height：" + display.getHeight()); WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE); DisplayMetrics outMetrics = new DisplayMetrics(); wm.getDefaultDisplay().getMetrics(outMetrics); mWidthScreen = outMetrics.widthPixels; mHeightScreen = outMetrics.heightPixels; LogUtils.e("Width：" + outMetrics.widthPixels); LogUtils.e("Height：" + outMetrics.heightPixels); LogUtils.e("xdpi：" + outMetrics.xdpi); LogUtils.e("ydpi：" + outMetrics.ydpi); LogUtils.e("densityDpi：" + outMetrics.densityDpi); LogUtils.e("density：" + outMetrics.density); LogUtils.e("scaledDensity：" + outMetrics.scaledDensity); LogUtils.e("spWidth：" + (outMetrics.widthPixels / outMetrics.scaledDensity + 0.5f)); LogUtils.e("spHeight：" + (outMetrics.heightPixels / outMetrics.scaledDensity + 0.5f)); LogUtils.e("dpWidth：" + (outMetrics.widthPixels / outMetrics.density + 0.5f)); LogUtils.e("dpHeight：" + (outMetrics.heightPixels / outMetrics.density + 0.5f)); DisplayMetrics resMetrics = getResources().getDisplayMetrics(); mHeightScreen = resMetrics.heightPixels; mWidthScreen = resMetrics.widthPixels; LogUtils.e("Width：" + resMetrics.widthPixels); LogUtils.e("Height：" + resMetrics.heightPixels); LogUtils.e("xdpi：" + resMetrics.xdpi); LogUtils.e("ydpi：" + resMetrics.ydpi); LogUtils.e("densityDpi：" + resMetrics.densityDpi); LogUtils.e("density：" + resMetrics.density); LogUtils.e("scaledDensity：" + resMetrics.scaledDensity); LogUtils.e("spWidth：" + (int)(resMetrics.widthPixels / resMetrics.scaledDensity + 0.5f)); LogUtils.e("spHeight：" + (int)(resMetrics.heightPixels / resMetrics.scaledDensity + 0.5f)); LogUtils.e("dpWidth：" + (resMetrics.widthPixels / resMetrics.density + 0.5f)); LogUtils.e("dpHeight：" + (resMetrics.heightPixels / resMetrics.density + 0.5f));
