在一個框架中創建多個部分，並使每個部分工作singleton

Question

我一直在努力的應用程序類似於Pic Frame,Insta collage一些如何成功地執行此任務，並創建代碼來使這樣的框架我已經使用了多點觸摸這是

MultiTouchview類

import java.util.ArrayList; 

import android.content.Context; 
import android.graphics.Bitmap; 
import android.graphics.BitmapFactory; 
import android.graphics.Canvas; 
import android.graphics.Color; 
import android.util.AttributeSet; 
import android.view.MotionEvent; 
import android.view.View; 


/** 
* Canvas View for the MultiTouch controller 
* @author 2dwarfs.com 
* 
*/ 

public class MultiTouchView extends View implements MultiTouchObjectCanvas<PinchWidget> { 

    private static final int UI_MODE_ROTATE = 1; 
    private static final int UI_MODE_ANISOTROPIC_SCALE = 2; 
    private int mUIMode = UI_MODE_ROTATE; 
    ArrayList<PinchWidget> alist = new ArrayList<PinchWidget>(); 

    private MultiTouchController<PinchWidget> mMultiTouchController = new MultiTouchController<PinchWidget>(this); 

    private int mWidth, mHeight; 

    private PinchWidget mPinchWidget; 
    private Context mContext; 

    public MultiTouchView(Context context) { 
     super(context); 
     //mContext = context; 
    } 

    public void clearCache(){ 
     alist.clear(); 
    } 

    public MultiTouchView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     mContext = context; 
    } 

    public MultiTouchView(Context context, AttributeSet attrs, int defStyle) { 
     super(context, attrs, defStyle); 
    } 

    public void setPinchWidget(Bitmap bitmap) { 
     mPinchWidget = new PinchWidget(bitmap); 
     alist.add(mPinchWidget); 
     mPinchWidget.init(mContext.getResources()); 
     invalidate(); 
    } 

    @Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     mWidth = resolveSize(getSuggestedMinimumWidth(), widthMeasureSpec); 
     mHeight = resolveSize(getSuggestedMinimumHeight(), heightMeasureSpec); 
     setMeasuredDimension(mWidth, mHeight); 
    } 

    @Override 
    public void onDraw(Canvas canvas) { 
     super.onDraw(canvas); 
     canvas.drawColor(Color.TRANSPARENT); 
     for(PinchWidget mmPinchWidget : alist) 
      mmPinchWidget.draw(canvas); 

    } 

    @Override 
    public boolean onTouchEvent(MotionEvent ev) { 
     return mMultiTouchController.onTouchEvent(ev); 
    } 

    @Override 
    public PinchWidget getDraggableObjectAtPoint(PointInfo pt) { 
     float x = pt.getX(), y = pt.getY(); 
     for(PinchWidget mPinchWidget : alist) { 
     if (mPinchWidget.containsPoint(x, y)) { 
      return mPinchWidget; 
     } 
     } 

     return null; 
    } 

    @Override 
    public void getPositionAndScale(PinchWidget pinchWidget, PositionAndScale objPosAndScaleOut) { 
     objPosAndScaleOut.set(pinchWidget.getCenterX(), pinchWidget.getCenterY(), 
       (mUIMode & UI_MODE_ANISOTROPIC_SCALE) == 0, 
       (pinchWidget.getScaleFactor() + pinchWidget.getScaleFactor())/2, 
       (mUIMode & UI_MODE_ANISOTROPIC_SCALE) != 0, 
       pinchWidget.getScaleFactor(), 
       pinchWidget.getScaleFactor(), 
       (mUIMode & UI_MODE_ROTATE) != 0, 
       pinchWidget.getAngle()); 
    } 

    @Override 
    public boolean setPositionAndScale(PinchWidget pinchWidget, PositionAndScale newImgPosAndScale, PointInfo touchPoint) { 
     boolean ok = pinchWidget.setPos(newImgPosAndScale, mUIMode, UI_MODE_ANISOTROPIC_SCALE, touchPoint.isMultiTouch()); 
     if(ok) { 
      invalidate(); 
     } 

     return ok; 
    } 

    @Override 
    public void selectObject(PinchWidget pinchWidget, PointInfo touchPoint) { 
     if(touchPoint.isDown()) { 
      mPinchWidget = pinchWidget; 
     } 

     invalidate(); 
    } 
} 

並用視圖類此幀像

Two.xml XML文件的兩幀

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="@color/transparent" 
    android:orientation="horizontal" > 

    <com.example.imageframe.MultiTouchView 
     android:orientation="horizontal" 
     android:id="@+id/firstone" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:layout_marginBottom="5.0dip" 
     android:layout_marginLeft="5.0dip" 
     android:layout_marginRight="5.0dip" 
     android:layout_marginTop="5.0dip" 
     android:layout_weight="0.5" 
     android:background="@drawable/back" /> 

    <com.example.imageframe.MultiTouchView 
     android:orientation="horizontal" 
     android:id="@+id/secondone" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:layout_marginBottom="5.0dip" 
     android:layout_marginRight="5.0dip" 
     android:layout_marginTop="5.0dip" 
     android:layout_weight="0.5" 
     android:background="@drawable/back" /> 

</LinearLayout> 

雖然編碼，我認爲它是一個非常複雜的方式來創建和使用這樣的幀。此外，這些框架特別是正方形/長方形，我無法動態地製作彎曲的邊框或改變框架形狀（使框架分區大/小或改變框架的形狀）。

我已經搜索了每一件事，找到一個合適的解決方案來實現這個解決方案，但沒有成功。

請儘快指導我動態地創建/操作/編輯框架，或者提供一些代碼片段來實現這種功能。

Answer 1

你可以使用片段。分別設計你的佈局。例如fragmentNumberOne.xml和fragmentNumberTwo.xml

在您的xml主要活動中放置一個FrameLayout;

<FrameLayout 
    android:id="@+id/content_frame" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" /> 

在您的活動;

Fragment fragment = new YourFragment(); 
Bundle args = new Bundle(); 
args.putInt("fragmentLayout", R.layout.fragmentNumberOne); 
fragment.setArguments(args); 

FragmentManager fragmentManager = getSupportFragmentManager(); 
fragmentManager.beginTransaction() 
     .replace(R.id.content_frame, fragment).commit(); 

並創建一個類;

public class YourFragment extends Fragment { 

public YourFragment() { 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    int fragmentLayout = getArguments().getInt("fragmentLayout"); 
    final View rootView = inflater 
      .inflate(fragmentLayout, container, false); 

    if (fragmentLayout == R.layout.fragmentNumberOne) { 
     ... 
     write your code here 
     ... 
    } else if (fragmentLayout == R.layout.fragmentNumberTwo) { 
     ... 
     write your code here 
     ... 
    } 

    return rootView; 
}
