答案 0 :(得分：2)
在这种情况下，您必须创建一个内容提供程序，用于将本地（应用程序的内部）文件共享到相机活动中。当您尝试从相机拍照时
试试这段代码： 内容提供商类
public class MyFileContentProvider extends ContentProvider {
public static final Uri CONTENT_URI =
Uri.parse("content://com.example.camerademo/");
private static final HashMap<String, String> MIME_TYPES = new
HashMap<String, String>();
static {
MIME_TYPES.put(".jpg", "image/jpeg");
MIME_TYPES.put(".jpeg", "image/jpeg");
}
@Override
public boolean onCreate() {
try {
File mFile = new File(getContext().getFilesDir(), "newImage.jpg");
if(!mFile.exists()) {
mFile.createNewFile();
}
getContext().getContentResolver().notifyChange(CONTENT_URI, null);
return (true);
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
@Override
public String getType(Uri uri) {
String path = uri.toString();
for (String extension : MIME_TYPES.keySet()) {
if (path.endsWith(extension)) {
return (MIME_TYPES.get(extension));
}
}
return (null);
}
@Override
public ParcelFileDescriptor openFile(Uri uri, String mode)
throws FileNotFoundException {
File f = new File(getContext().getFilesDir(), "newImage.jpg");
if (f.exists()) {
return (ParcelFileDescriptor.open(f,
ParcelFileDescriptor.MODE_READ_WRITE));
}
throw new FileNotFoundException(uri.getPath());
}
@Override
public Cursor query(Uri url, String[] projection, String selection,
String[] selectionArgs, String sort) {
throw new RuntimeException("Operation not supported");
}
@Override
public Uri insert(Uri uri, ContentValues initialValues) {
throw new RuntimeException("Operation not supported");
}
@Override
public int update(Uri uri, ContentValues values, String where,
String[] whereArgs) {
throw new RuntimeException("Operation not supported");
}
@Override
public int delete(Uri uri, String where, String[] whereArgs) {
throw new RuntimeException("Operation not supported");
}
}
Home.java：
public class Home extends Activity implements OnClickListener{
/** Called when the activity is first created. */
private final int CAMERA_RESULT = 1;
private final String Tag = getClass().getName();
Button button1;
ImageView imageView1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button1 = (Button)findViewById(R.id.button1);
imageView1 = (ImageView)findViewById(R.id.imageView1);
button1.setOnClickListener(this);
}
public void onClick(View v) {
PackageManager pm = getPackageManager();
if (pm.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, MyFileContentProvider.CONTENT_URI);
startActivityForResult(i, CAMERA_RESULT);
} else {
Toast.makeText(getBaseContext(), "Camera is not available",
Toast.LENGTH_LONG).show();
} }
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent
data) {
super.onActivityResult(requestCode, resultCode, data);
Log.i(Tag, "Receive the camera result");
if (resultCode == RESULT_OK && requestCode == CAMERA_RESULT) {
File out = new File(getFilesDir(), "newImage.jpg");
if(!out.exists()) {
Toast.makeText(getBaseContext(),
"Error while capturing image", Toast.LENGTH_LONG)
.show();
return;
}
Bitmap mBitmap = BitmapFactory.decodeFile(out.getAbsolutePath());
imageView1.setImageBitmap(mBitmap);
}
}
@Override
protected void onDestroy() {
super.onDestroy();
imageView1 = null;
}
}
hope it will help you,otherwise u will contact me my email
