如何拍摄、裁剪和分享屏幕截图?
How to take,crop and share screenshot?
我有一个代码要获取,保存然后分享 Activity 的屏幕截图。我的问题是我只想取 activity 的中心,所以我添加了这段代码
private Bitmap cropBitmap(Bitmap bitmap) {
Bitmap bm = Bitmap.createBitmap(bitmap, 10, 10, 500, 500);
return bm;
}
但它仍然是原始屏幕截图,请帮助我,我尝试了很多解决方案,但似乎我不知道如何应用这些解决方案,因为我在编码方面非常业余。所以我希望能帮助我,请根据我的代码给我正确的解决方案。非常非常感谢
@Override
public void onClick(View v) {
Bitmap bitmap = takeScreenshot();
cropBitmap(bitmap);
saveBitmap(bitmap);
shareIt();
}
public Bitmap takeScreenshot() {
View v1 = getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
return bitmap;
}
private Bitmap cropBitmap(Bitmap bitmap) {
Bitmap bm = Bitmap.createBitmap(bitmap, 10, 10, 500, 500);
return bm;
}
private void saveBitmap(Bitmap bitmap) {
imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png"); ////File imagePath
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
Log.e("GREC", e.getMessage(), e);
} catch (IOException e) {
Log.e("GREC", e.getMessage(), e);
}
}
private void shareIt() {
Uri myUri = Uri.fromFile(imagePath);
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("image/*");
sharingIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
String shareBody = "My highest score with screen shot";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "My Catch score");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
sharingIntent.putExtra(Intent.EXTRA_STREAM, myUri);
startActivity(Intent.createChooser(sharingIntent, "Share via"));
}
});
displayResults();
这样试试:
Bitmap bitmap = takeScreenshot();
Bitmap bitmapCropped = cropBitmap(bitmap);
saveBitmap(bitmapCropped );
