Android拍照与相册选取精简-优快云博客

本文介绍如何在Android应用中实现拍照及从相册选择图片的功能。通过设置不同的返回码来区分拍照与选取操作，并详细说明了启动相机与相册的Intent配置，包括临时图片路径设置、获取图片路径等关键步骤。

//返回码 ：本地图库
private static final int RESULT_IMAGE = 100;
//返回码 ：相机
private static final int RESULT_CAMERA = 200;
//IMAGE TYPE
private static final String IMAGE_TYPE = "image/*";

//Temp照片路径
public static String TEMP_IMAGE_PATH;

//拍照
	TEMP_IMAGE_PATH = Environment.getExternalStorageDirectory().getPath()+"/temp.png";
	Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
	Uri photoUri = Uri.fromFile(new File(TEMP_IMAGE_PATH));
	intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
	startActivityForResult(intent,RESULT_CAMERA);
//相册
	Intent intent = new Intent(Intent.ACTION_PICK,null);
	intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,IMAGE_TYPE);
	startActivityForResult(intent,RESULT_IMAGE);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(resultCode == RESULT_OK){
        if(requestCode == RESULT_IMAGE && data != null){
            //相册
            Cursor cursor = this.getContentResolver().query(data.getData(),null,null,null,null);
            cursor.moveToFirst();
            String imagePath = cursor.getString(cursor.getColumnIndex("_data")); 
            cursor.close();
      
        }
        else if(requestCode == RESULT_CAMERA){
            //相机 图片保存到Uri中
        }
    }
}
