直播网站源码，Android获取屏幕高宽

The first：通过WindowManager来获取，个人建议使用

<br>import android.content.Context;<br>import android.util.DisplayMetrics;<br>import android.view.WindowManager;<br> <br>public class ScreenUtil {<br> <br>    private static ScreenUtil mInstance = null;<br>    private final int mWidth, mHeight;<br> <br>    public static ScreenUtil getInstance(Context context){<br>        if (null == mInstance){<br>            synchronized (ScreenUtil.class){<br>                if (null == mInstance){<br>                    mInstance = new ScreenUtil(context);<br>                }<br>            }<br>        }<br>        return mInstance;<br>    }<br> <br>    private ScreenUtil(Context context){<br>        //获取系统window服务<br>        WindowManager manager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);<br>        //获取屏幕参数<br>        DisplayMetrics metrics = new DisplayMetrics();<br>        manager.getDefaultDisplay().getMetrics(metrics);<br>        mWidth = metrics.widthPixels;<br>        mHeight = metrics.heightPixels;<br>    }<br> <br>    public int getWidth(){<br>        return mWidth;<br>    }<br> <br>    public int getHeight(){<br>        return mHeight;<br>    }<br>}

The second：也是通过WindowManager来获取，与第一种方式不同的是获取WindowManager的方式

<br>import android.app.Activity;<br>import android.util.DisplayMetrics;<br> <br>public class ScreenUtil {<br> <br>    private static ScreenUtil mInstance = null;<br>    private final int mWidth, mHeight;<br> <br>    public static ScreenUtil getInstance(Activity activity){<br>        if (null == mInstance){<br>            synchronized (ScreenUtil.class){<br>                if (null == mInstance){<br>                    mInstance = new ScreenUtil(activity);<br>                }<br>            }<br>        }<br>        return mInstance;<br>    }<br> <br>    private ScreenUtil(Activity activity){<br>        DisplayMetrics metrics = new DisplayMetrics();<br>        activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);<br>        mWidth = metrics.widthPixels;<br>        mHeight = metrics.heightPixels;<br>    }<br> <br>    public int getWidth(){<br>        return mWidth;<br>    }<br> <br>    public int getHeight(){<br>        return mHeight;<br>    }<br>}
