Android调用相机拍照并返回路径和调用系统图库选择图片


调用系统图库：

Intent intent = new Intent(Intent.ACTION_PICK,MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(intent, REQUEST_CODE_IMAGE);

获取图片路径

@Override

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

   super.onActivityResult(requestCode, resultCode, data);

   if (requestCode == REQUEST_CODE_IMAGE && resultCode == RESULT_OK) {

      Uri uri = data.getData();

      Cursor cursor = getContentResolver().query(uri, null, null, null,null);

      if (cursor != null && cursor.moveToFirst()) {

          String path = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA));

    }

   }

 }

调用相机返回路径1：

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

startActivityForResult(intent, REQUEST_CODE_CAMERA);

@Override

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

   super.onActivityResult(requestCode, resultCode, data);

   if (requestCode == REQUEST_CODE_CAMERA && resultCode == RESULT_OK) {

      Bundle bundle = data.getExtras();

     // 获取相机返回的数据，并转换为Bitmap图片格式，这是缩略图
      Bitmap bitmap = (Bitmap) bundle.get("data");

   }

 }

调用相机返回路径2：

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

//path为保存图片的路径，执行完拍照以后能保存到指定的路径下

File file = new File(path);

Uri imageUri = Uri.fromFile(file );

intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);

startActivityForResult(intent, REQUEST_CODE_CAMERA);

 

@Override

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

   super.onActivityResult(requestCode, resultCode, data);

   if (requestCode == REQUEST_CODE_CAMERA && resultCode == RESULT_OK) {

       //直接取之前保存的路径

   }

 }
