1.有時候拍照的圖檔比實際的要小
這可能和版本有管
不過在2.0上以上 可以沒問題
在1.6一下即使你用hw.camera.maxHorizontalPixels 和 hw.camera.maxVerticalPixels.
都會得到原大小的1/4
Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File out = new File(Environment.getExternalStorageDirectory(), "camera.jpg");
Uri uri = Uri.fromFile(out);
imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
imageCaptureIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(imageCaptureIntent, RESULT_CAPTURE_IMAGE);
上述沒有問題
上面的存入制定目錄。存入存放圖檔的地方
SimpleDateFormat timeStampFormat = new SimpleDateFormat("yyyyMMddHHmmssSS");
String filename = timeStampFormat.format(new Date());
ContentValues values = new ContentValues();
values.put(Media.TITLE, filename);
values.put(Media.DESCRIPTION, "Image from Android Emulator");
photoUri =
getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent inttPhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
inttPhoto.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
startActivityForResult(inttPhoto, 0);
2 然後相關處理就是
private void saveFullImage() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(), "test.jpg");
outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, TAKE_PICTURE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if ((requestCode == TAKE_PICTURE) && (resultCode == Activity.RESULT_OK)) {
// Check if the result includes a thumbnail Bitmap
if (data == null) {
// TODO Do something with the full image stored
// in outputFileUri. Perhaps copying it to the app folder
}
}
}
3. 一個可以相容的處理方法：
public boolean hasImageCaptureBug() {
// list of known devices that have the bug
ArrayList<String> devices = new ArrayList<String>();
devices.add("android-devphone1/dream_devphone/dream");
devices.add("generic/sdk/generic");
devices.add("vodafone/vfpioneer/sapphire");
devices.add("tmobile/kila/dream");
devices.add("verizon/voles/sholes");
devices.add("google_ion/google_ion/sapphire");
return devices.contains(android.os.Build.BRAND + "/" + android.os.Build.PRODUCT + "/"
+ android.os.Build.DEVICE);
}
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (hasImageCaptureBug()) {
i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File("/sdcard/tmp")));
} else {
i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
}
startActivityForResult(i, mRequestCode);
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
switch (requestCode) {
case GlobalConstants.IMAGE_CAPTURE:
Uri u;
if (hasImageCaptureBug()) {
File fi = new File("/sdcard/tmp");
try {
u = Uri.parse(android.provider.MediaStore.Images.Media.insertImage(getContentResolver(), fi.getAbsolutePath(), null,null));
if (!fi.delete()) {
Log.i(t, "Failed to delete " + fi);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
} else { = intent.getData();
}
}
u
第三種方法雖然可以解決版本問題
對存在bug的版本 得到的大小也隻有512寬 版本正常的 可以得到想要大小
還有一個缺點 可能版本的bug被修正 那樣你的bug函數就需要修改
