我们大家都在用电脑的时候,用过截屏的功能,有的时候截屏给我们带来了很多的方便,那么我们现在怎么样才能在android中实现这个功能那,下面我们就用代码来实现这个对我们很方便的功能。
java代码:
import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import android.app.Activity; import android.graphics.Bitmap; import android.graphics.Rect; import android.view.View; public class ScreenShot { // 获取指定Activity的截屏,保存到png文件 private static Bitmap takeScreenShot(Activity activity){ //View是你需要截图的View View view = activity.getWindow().getDecorView(); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); Bitmap b1 = view.getDrawingCache(); //获取状态栏高度 Rect frame = new Rect(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); int statusBarHeight = frame.top; System.out.println(statusBarHeight); //获取屏幕长和高 int width = activity.getWindowManager().getDefaultDisplay().getWidth(); int height = activity.getWindowManager().getDefaultDisplay().getHeight(); //去掉标题栏 //Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455); Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight); view.destroyDrawingCache(); return b; } //保存到sdcard private static void savePic(Bitmap b,String strFileName){ FileOutputStream fos = null; try { fos = new FileOutputStream(strFileName); if (null != fos) { b.compress(Bitmap.CompressFormat.PNG, 90, fos); fos.flush(); fos.close(); } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } //程序入口 public static void shoot(Activity a){ ScreenShot.savePic(ScreenShot.takeScreenShot(a), "sdcard/xx.png"); } }
