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

}  }
