| SurfaceViewをフラグメント上に追加したい |
| surfaceViewをフラグメントのViewにプログラムから追加したいのですがsurfaceViewCreatedを呼んでくれません |
| ```ここに言語を入力 |
| public class EditPictureFragment extends Fragment { |
| private final int WC = ViewGroup.LayoutParams.WRAP_CONTENT; |
| private final int MP = ViewGroup.LayoutParams.MATCH_PARENT; |
| public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState){ |
| View view = inflater.inflate(R.layout.layout_edit_picture, container, false); |
| Uri uri = Uri.parse(getArguments().getString("uri")); |
| LinearLayout linearLayout =(LinearLayout)view.findViewById(R.id.linearLayout2); |
| PictureSurfaceView pictureSurfaceView = new PictureSurfaceView(getActivity(),uri); |
| linearLayout.addView(pictureSurfaceView, 0, new LinearLayout.LayoutParams(WC, WC)); |
| return view; |
| } |
| ``` |
| fragmentで追加しているレイアウトリソースがこれです |
| ```ここに言語を入力 |
| <?xml version="1.0" encoding="utf-8"?> |
| <ScrollView |
| android:id="@+id/ScrollView2" |
| android:layout_height="fill_parent" |
| android:layout_width="fill_parent" |
| xmlns:android="http://schemas.android.com/apk/res/android" |
| > |
| <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" |
| android:orientation="vertical" android:layout_width="fill_parent" |
| android:layout_height="wrap_content" |
| android:id="@+id/linearLayout2"> |
| </LinearLayout> |
| </ScrollView> |
| ``` |
| 下がsurfaceViewのクラスです |
| ```ここに言語を入力 |
| public class PictureSurfaceView extends SurfaceView implements SurfaceHolder.Callback,Runnable{ |
| Canvas canvas; |
| Bitmap picture; |
| SurfaceHolder s_holder; |
| Float scale; |
| Uri uri; |
| Context context; |
| public PictureSurfaceView(Context context,Uri uri) { |
| super(context); |
| this.context = context; |
| s_holder = getHolder(); |
| this.uri = uri; |
| s_holder.addCallback(this); |
| // deprecated setting, but required on Android versions prior to 3.0 |
| } |
| @Override |
| public void surfaceCreated(SurfaceHolder surfaceHolder) { |
| float scaleX = getWidth(); |
| float scaleY = getHeight(); |
| scale = scaleX > scaleY ? scaleY : scaleX; |
| final BitmapFactory.Options options = new BitmapFactory.Options(); |
| ContentResolver cr = context.getContentResolver(); |
| options.inJustDecodeBounds = true; |
| try { |
| BitmapFactory.decodeStream(cr.openInputStream(uri), null, options); |
| } catch (FileNotFoundException e) { |
| e.printStackTrace(); |
| } |
| int width = getWidth(); |
| int height = (int) (width * (float) options.outHeight / (float) options.outWidth); |
| picture=BitMapHandler.decodeSampledBitmapFromUri(context,uri,width,height); |
| Log.d("message","surfaceView = "+picture.toString()); |
| } |
| @Override |
| public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) { |
| } |
| @Override |
| public void surfaceDestroyed(SurfaceHolder surfaceHolder) { |
| } |
| @Override |
| public void run() { |
| while(true){ |
| canvas = s_holder.lockCanvas(); |
| draw(); |
| s_holder.unlockCanvasAndPost(canvas); |
| canvas.translate(getWidth()/2*scale, getHeight()/2*scale); // 画面の中央になるように移動させる |
| canvas.scale(scale, scale); |
| try{ |
| Thread.sleep(100);//次の描画まで100msecの間隔を空ける |
| //（フレームレートを厳守するのであれば，sleepさせるのではなく，描画処理を一定間隔で呼び出すようにする） |
| }catch(InterruptedException e){ |
| e.printStackTrace(); |
| } |
| } |
| } |
| public void draw(){ |
| Paint paint = new Paint(); |
| canvas.drawBitmap(picture,0,0,paint); |
| } |
| } |
| ``` |
| ``` |
| 何が間違っているのでしょうか...お願いします |
