安卓工作室拍照

嘿，我跟着教程在android工作室项目中拍照，但我的应用程序崩溃没有任何日志错误。任何帮助，将不胜感激。如果有人知道如何从画廊添加图片到图像视图，那将是非常棒的。安卓工作室拍照

public class MainActivity extends Activity { 
    Button bn; 
    int REQUEST_CODE = 1; 
    ImageView IMG; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     bn = (Button) findViewById(R.id.bn); 
     IMG = (ImageView) findViewById(R.id.img); 
     bn.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
       if(i.resolveActivity(getPackageManager())!= null){ 
        startActivityForResult(i,REQUEST_CODE); 
       } 
      } 
     }); 
     } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    public void onActivityResult(int requestcode, int resultcode, Intent data){ 
     if(requestcode == REQUEST_CODE && resultcode == RESULT_OK) 
     { 
      Bundle extras = data.getExtras(); 
      Bitmap imageBitmap = (Bitmap) extras.get("data"); 
      IMG.setImageBitmap(imageBitmap); 
     } 
    } 

}

您好我想你问到拍摄照片从画廊或相机，那么你要到的图像设置为ImageView的。如果我是正确的，然后按照下面的代码

private void openCamera() { 
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd_HH_mm_ss"); 
String currentTimeStamp = dateFormat.format(new Date()); 
f = new File(android.os.Environment.getExternalStorageDirectory(), currentTimeStamp); 
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f)); 
startActivityForResult(intent, 1);

}

private void openGallery() { 
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
intent.setType("image/*"); 
startActivityForResult(Intent.createChooser(intent, "Select File"), REQUEST_GALLERY);

}

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
super.onActivityResult(requestCode, resultCode, data); 
if (resultCode == RESULT_OK) { 
    if (requestCode == 1) { 
     try { 
      String click = f.getAbsolutePath(); 
      SQLiteDatabase db = dbHelper.getWritableDatabase(); 
      ContentValues values = new ContentValues(); 
      values.put(User_Detail.KEY_ALBUM_IMAGE_PATH, click); 
      values.put(User_Detail.USER_ID, Utlity.user_id); 
      values.put(User_Detail.KEY_ID_ALBUM_REF, album_id); 
      long loginStat = db.insert(User_Detail.TABLE_4, null, values); 
      loadData(album_id); 

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
} else if (requestCode == 2) { 

     Uri selectedImage = data.getData(); 
     String[] filePath = { MediaStore.Images.Media.DATA }; 
     Cursor c = getContentResolver().query(selectedImage, filePath, null, null, null); 
     c.moveToFirst(); 
     int columnIndex = c.getColumnIndex(filePath[0]); 
     picturePath = c.getString(columnIndex); 
     if (picturePath != null && picturePath.length() > 1) { 
      ContentValues va = new ContentValues(); 
     } else { 
     } 
     SQLiteDatabase db = dbHelper.getWritableDatabase(); 
     String image_path = picturePath; 
     ContentValues values = new ContentValues(); 
     values.put(User_Detail.KEY_ALBUM_IMAGE_PATH, image_path); 
     values.put(User_Detail.USER_ID, Utlity.user_id); 
     values.put(User_Detail.KEY_ID_ALBUM_REF, album_id); 
     long loginStat = db.insert(User_Detail.TABLE_4, null, values); 
     loadData(album_id); 
     c.close(); 
     Log.w("path of image from gallery......******************.........", picturePath + ""); 
    } 
}

}

现在你得到selectd图片或者拍摄图像的ImagePath的。现在你需要设置你的图像视图，然后创建一个Adapter类，它扩展了BaseAdapter，并且在那个适配器类中你可以通过将Imagepath转换成位图来设置这个图像
