方法是获取当前的view,然后保存为图片
public class ScreenShot {
// 获取指定Activity的截屏,保存到png文件
String filenameTemp ="/mnt/sdcard/temp";
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;
Log.i("TAG", "" + 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;
