第一种：5.0 之后开放了截屏的方法
if (Build.VERSION.SDK_INT >= 21) {
startActivityForResult(((MediaProjectionManager) getSystemService("media_projection")).createScreenCaptureIntent(),1);
} else {
Log.e("TAG", "版本过低,无法截屏");
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQUEST_MEDIA_PROJECTION: {
if (resultCode == -1 && data != null) {
parseData(data);
}
}
}
}
private void parseData(Intent data){
MediaProjection mMediaProjection = (MediaProjectionManager).getSystemService(
Context.MEDIA_PROJECTION_SERVICE).getMediaProjection(Activity.RESULT_OK,data);
ImageReader mImageReader = ImageReader.newInstance(
getScreenWidth(),
getScreenHeight(),
PixelFormat.RGBA_8888,1);
VirtualDisplay mVirtualDisplay = mMediaProjection.createVirtualDisplay("screen-mirror",
getScreenWidth(),
getScreenHeight(),
Resources.getSystem().getDisplayMetrics().densityDpi,
DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR,
mImageReader.getSurface(), null, null);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
Image image = mImageReader.acquireLatestImage();
// TODO 将image保存到本地即可
}
}, 300);
mVirtualDisplay.release();
mVirtualDisplay = null;
}
第二种：使用 decorView
public static Bitmap capture(Activity activity) {
activity.getWindow().getDecorView().setDrawingCacheEnabled(true);
Bitmap bmp = activity.getWindow().getDecorView().getDrawingCache();
return bmp;
}
public static Bitmap shotActivity(Activity ctx) {
View view = ctx.getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap bp = Bitmap.createBitmap(view.getDrawingCache(), 0, 0, view.getMeasuredWidth(),
view.getMeasuredHeight());
view.setDrawingCacheEnabled(false);
view.destroyDrawingCache();
return bp;
}
长截屏 ScrollView 截屏
public static Bitmap shotScrollView(ScrollView scrollView) {
int h = 0;
Bitmap bitmap = null;
for (int i = 0; i |
