我认为你的意思是以编程方式从手机桌面上拍摄照片？如果是这样，使用意图拍照。你可以搜索网络意图拍照。
你可以使用这块代码。

private static final int TAKE_PICTURE = 1;  
private Uri imageUri; 

public void takePhoto(View view) { 
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg"); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, 
      Uri.fromFile(photo)); 
    imageUri = Uri.fromFile(photo); 
    startActivityForResult(intent, TAKE_PICTURE); 
} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    switch (requestCode) { 
    case TAKE_PICTURE: 
     if (resultCode == Activity.RESULT_OK) { 
      Uri selectedImage = imageUri; 
      getContentResolver().notifyChange(selectedImage, null); 
      ImageView imageView = (ImageView) findViewById(R.id.ImageView); 
      ContentResolver cr = getContentResolver(); 
      Bitmap bitmap; 
      try { 
       bitmap = android.provider.MediaStore.Images.Media 
       .getBitmap(cr, selectedImage); 

       imageView.setImageBitmap(bitmap); 
       Toast.makeText(this, selectedImage.toString(), 
         Toast.LENGTH_LONG).show(); 
      } catch (Exception e) { 
       Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT) 
         .show(); 
       Log.e("Camera", e.toString()); 
      } 
     } 
    } 
}
