Android 将相机的照片保存到内存中

我是这个网站和安卓的新手。如何将相机的图片保存到特定文件夹中并将图片的名称也保存到sqlite数据库中。

 public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
 //  setContentView(R.layout.camera);
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);  
    File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,
            Uri.fromFile(photo));
    imageUri = Uri.fromFile(photo);

    startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);  
    onActivityResult(1337, 0, cameraIntent);

}



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

        if (resultCode == CAMERA_PIC_REQUEST) {

    }

我打开了相机活动。如何获取图片名称和图片名称将其保存到特定位置？

请帮我解决这个问题。

先感谢您。

我正在调用相机

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

并像这样保存到 SD 卡

final ImageView img = new ImageView(this);
img.setLayoutParams(new LayoutParams(100, 100));
image2 = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(image2);
String incident_ID = IncidentFormActivity.incident_id;
//l2.addView(img);
    imagepath="/sdcard/RDMS/"+incident_ID+ x + ".png";
File file = new File(imagepath);
try {
bm = Bitmap.createScaledBitmap( image2,400, 300, true);
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bm.compress(CompressFormat.PNG, 90, ostream);
ostream.close(); 
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),"yourfirst  error message is "
+ e.toString(), 1000).show();
        }

I'm calling camera

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

and saving to sd card like this

final ImageView img = new ImageView(this);
img.setLayoutParams(new LayoutParams(100, 100));
image2 = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(image2);
String incident_ID = IncidentFormActivity.incident_id;
//l2.addView(img);
    imagepath="/sdcard/RDMS/"+incident_ID+ x + ".png";
File file = new File(imagepath);
try {
bm = Bitmap.createScaledBitmap( image2,400, 300, true);
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bm.compress(CompressFormat.PNG, 90, ostream);
ostream.close(); 
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),"yourfirst  error message is "
+ e.toString(), 1000).show();
        }

您可能需要将该行更改

 if (resultCode == CAMERA_PIC_REQUEST) {

为

 if (requestCode == CAMERA_PIC_REQUEST) {

You may need to change the line

 if (resultCode == CAMERA_PIC_REQUEST) {

 if (requestCode == CAMERA_PIC_REQUEST) {

您已经在保存图片了。您在 MediaStore.EXTRA_OUTPUT 中提供了位置。
