Android 相机 相册

调用相机：

```java
private static final int REQUEST_CODE_CAMERA = 1;

private void openCamera() {
    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) {
        // 获取拍照结果
        Bundle extras = data.getExtras();
        Bitmap bitmap = (Bitmap) extras.get("data");
        // 处理拍照结果
    }
}
```

调用相册：

```java
private static final int REQUEST_CODE_ALBUM = 2;

private void openAlbum() {
    Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(intent, REQUEST_CODE_ALBUM);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_ALBUM && resultCode == RESULT_OK) {
        // 获取相册选中的图片
        Uri uri = data.getData();
        String[] projection = {MediaStore.Images.Media.DATA};
        Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
        cursor.moveToFirst();
        int columnIndex = cursor.getColumnIndex(projection[0]);
        String filePath = cursor.getString(columnIndex);
        cursor.close();
        // 处理选中的图片
    }
}
