项目中偶尔会用到截屏分享，于是就有了下面这个截屏的方法~
下面得saveImage()方法就是保存当前Activity对应的屏幕所有内容的截屏保存。
private void saveImage() {
// SD卡保存路径
String savePath = Environment.getExternalStorageDirectory() + "/temp.png";
// showProgress("请稍候", "正在保存图片……");
saveMyBitmap(getBitmapFromRootView(getWindow().getDecorView()), savePath);
}
// 获取view并转换成bitmap图片
private static Bitmap getBitmapFromRootView(View view) {
view.setDrawingCacheEnabled(true);
Bitmap bmp = Bitmap.createBitmap(view.getDrawingCache());
view.setDrawingCacheEnabled(false);
if (bmp != null) {
return bmp;
} else {
return null;
}
}
// 把bitmao图片保存到对应的SD卡路径中
private void saveMyBitmap(Bitmap mBitmap, String path) {
File f = new File(path);
try {
f.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
FileOutputStream fOut = null;
try {
fOut = new FileOutputStream(f);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
if (mBitmap != null) {
// 保存格式为PNG 质量为100
mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
}
try {
fOut.flush();
} catch (IOException e) {
e.printStackTrace();
}
try {
fOut.close();
} catch (IOException e) {
e.printStackTrace();
}
}
