现在已经5天了，没有人帮忙！！请问谁能帮帮我
我有一个问题，并且仅适用于 Samsumg S3 手机。我正在尝试从 android 的相机服务中拍摄 4 张图像。
问题是当我尝试为其他手机执行此操作时，相同的代码可以正常工作，但显示三星 S3 手机存在问题。
我想做的是有4个Imageview，在每个imageview的onclick上，我可以根据用户的选择打开相机服务或图库服务。单击或选择图像后，该图像将设置在单击的特定图像视图上。
所以我可以一张一张地设置所有 4 张图像。这适用于其他手机和其他三星手机，但三星 S3 似乎有问题。
谁能帮帮我。
这是我在 imageView 上拍摄图像的代码。
我的 Oncreate 方法
public class Add_image extends Activity {
ImageView imgview1, imgview2, imgview3, imgview4;
private static int RESULT_LOAD_IMAGE = 1;
private static final int CAMERA_IMAGE_CAPTURE = 0;
private static final int PICK_FROM_GALLERY = 2;
int CAMERA_PIC_REQUEST = 1337;
String SD_CARD_IMAGE_PATH = null;
byte b[];
String largeImagePath = "";
Uri uriLargeImage;
Uri uriThumbnailImage;
private static final int OG = 4;
int flag = 0, orientation;
String bal, picturePath, bal1, bal2, bal3, bal4;
int flagg = 0;
Cursor myCursor, cursor1;
Bitmap thumbnail = null;
TextView t5, t6, t7, t8;
// SharedPreferences pic1, pic2, pic3, pic4;
Button btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.image);
imgview1 = (ImageView) this.findViewById(R.id.imageView1);
imgview1.setOnClickListener(click_img1);
imgview2 = (ImageView) this.findViewById(R.id.imageView2);
imgview2.setOnClickListener(click_img2);
imgview3 = (ImageView) this.findViewById(R.id.imageView3);
imgview3.setOnClickListener(click_img3);
imgview4 = (ImageView) this.findViewById(R.id.imageView4);
imgview4.setOnClickListener(click_img4);
t5 = (TextView) findViewById(R.id.textView5);
t5.setVisibility(View.VISIBLE);
t6 = (TextView) findViewById(R.id.textView6);
t6.setVisibility(View.VISIBLE);
t7 = (TextView) findViewById(R.id.textView7);
t7.setVisibility(View.VISIBLE);
t8 = (TextView) findViewById(R.id.textView8);
t8.setVisibility(View.VISIBLE);
btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(btn_click);
if (savedInstanceState != null) {
Bitmap carpic;
String B1 = savedInstanceState.getString("message");
// Toast.makeText(this, "SavedYeah"+B1, Toast.LENGTH_LONG).show();
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inSampleSize = OG;
carpic = BitmapFactory.decodeFile((B1), opts);
System.gc();
if (carpic != null) {
imageCam(carpic);
}
}
}
不同的按钮点击
public View.OnClickListener btn_click = new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Add_image.this, Add.class);
startActivity(intent);
}
};
private View.OnClickListener click_img1 = new View.OnClickListener() {
@Override
public void onClick(View v) {
flag = 1;
openNewGameDialog();
}
};
private View.OnClickListener click_img2 = new View.OnClickListener() {
@Override
public void onClick(View v) {
flag = 2;
openNewGameDialog();
}
};
private View.OnClickListener click_img3 = new View.OnClickListener() {
@Override
public void onClick(View v) {

openNewGameDialog();
}
};
private View.OnClickListener click_img4 = new View.OnClickListener() {
@Override
public void onClick(View v) {
flag = 4;
openNewGameDialog();
}
};
我的 openNewGameDialog() 方法来检查制造商和相机服务
String[] B = { "Camera", "Gallery", "Delete Image" };
private void openNewGameDialog() {
new AlertDialog.Builder(this).setItems(B,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialoginterface, int i) {
if (i == 0) {
String BX1 = android.os.Build.MANUFACTURER;
if (BX1.equalsIgnoreCase("samsung")) {
// Toast.makeText(getApplicationContext(),
// "Device man"+BX1, Toast.LENGTH_LONG).show();
Intent intent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent,
CAMERA_IMAGE_CAPTURE);
} else {
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent,
CAMERA_PIC_REQUEST);
}
}
else if (i == 1) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, RESULT_LOAD_IMAGE);
} else if (i == 2) {
if (flag == 1) {
imgview1.setImageDrawable(null);
t5.setVisibility(View.VISIBLE);
}
if (flag == 2) {
imgview2.setImageDrawable(null);
t7.setVisibility(View.VISIBLE);
}
if (flag == 3) {
imgview3.setImageDrawable(null);
t6.setVisibility(View.VISIBLE);
}
if (flag == 4) {
imgview4.setImageDrawable(null);
t8.setVisibility(View.VISIBLE);
}
}
}
}).show();
}
imageCam() 方法将图像设置为 ImageView
public void imageCam(Bitmap thumbnail) {
Bitmap photo = thumbnail;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 70, bos);
b = bos.toByteArray();
bal = Base64.encodeBytes(b);
// ImageView imageview = (ImageView) findViewById(R.id.imageView1);
String BX1 = android.os.Build.MANUFACTURER;
if (BX1.equalsIgnoreCase("samsung") && flagg == 0) {
}
if (flag == 1) {
bal1 = bal;
t5.setVisibility(View.GONE);
imgview1.setImageBitmap(photo);
// Toast.makeText(getApplicationContext(), "Image1=" + bal1,
// Toast.LENGTH_LONG).show();
} else if (flag == 2) {
bal2 = bal;
t7.setVisibility(View.GONE);
imgview2.setImageBitmap(photo);
// Toast.makeText(getApplicationContext(), "Image2=" + bal2,
// Toast.LENGTH_LONG).show();
} else if (flag == 3) {
bal3 = bal;
t6.setVisibility(View.GONE);
imgview3.setImageBitmap(photo);
// Toast.makeText(getApplicationContext(), "Image3=" + bal3,
// Toast.LENGTH_LONG).show();
} else if (flag == 4) {
bal4 = bal;
t8.setVisibility(View.GONE);
imgview4.setImageBitmap(photo);
// Toast.makeText(getApplicationContext(), "Image4=" + bal4,
// Toast.LENGTH_LONG).show();
}
Add ad = new Add();
ad.image_save(bal1, bal2, bal3, bal4);
// flag=0;
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString("message", largeImagePath);
outState.putString("Gallerymessage", picturePath);
}
