我写了一张SMIL的堆肥器,用于一个班子,我正计划使信管支持输血和输电,这样你就可以把照片和文字放到你们的希望之中。 我先谈一些例子,我自己也做了一些发言,但当我去执行我的项目的拖延和下降时,我没有工作。 主要法典是:

public class ComposerActivity extends Activity {
    /** Called when the activity is first created. */

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.composer);

    Button add = (Button)findViewById(R.id.addBtn);
    ...

    add.setOnClickListener(mClick);
    ...
}

OnClickListener mClick = new OnClickListener() {
    @Override
    public void onClick(View v){        
        if(v.getId() == R.id.addBtn)
        {
            FrameLayout fl = (FrameLayout)findViewById(R.id.Canvas); 
            LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
            View itemView = inflater.inflate(R.layout.image_add, null);

            View image = (View)itemView.findViewById(R.id.image);   
            image.setBackgroundResource(R.drawable.icon); 

            fl.addView(itemView, new FrameLayout.LayoutParams(40, 40));  

            image.setOnTouchListener(drag);
        }
        ...

OnTouchListener drag = new OnTouchListener(){
    @Override 
    public boolean onTouch(View v, MotionEvent event){ 
        FrameLayout.LayoutParams par = (LayoutParams) v.getLayoutParams(); 
        switch(v.getId()){//What is being touched 
            case R.id.image:{//Which action is being taken 
                switch(event.getAction()){ 
                    case MotionEvent.ACTION_MOVE:{  
                        par.topMargin = (int)event.getRawY() - (v.getHeight()); 
                        par.leftMargin = (int)event.getRawX() - (v.getWidth()/2); 
                        v.setLayoutParams(par); 
                        break; 
                    }//inner case MOVE 
                    case MotionEvent.ACTION_UP:{ 
                        par.height = 40; 
                        par.width = 40; 
                        par.topMargin = (int)event.getRawY() - (v.getHeight()); 
                        par.leftMargin = (int)event.getRawX() - (v.getWidth()/2); 
                        v.setLayoutParams(par); 
                        break; 
                    }//inner case UP 
                    case MotionEvent.ACTION_DOWN:{ 
                        par.height = 60; 
                        par.width = 60; 
                        v.setLayoutParams(par); 
                        break; 
                    }//inner case UP 
                }//inner switch 
                break; 
            }//case image
        }//switch 
            return true; 
        }//onTouch 
    };//drag
}

compos:

...
<FrameLayout android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_below="@+id/TopBar" 
    android:layout_above="@+id/addBtn" 
    android:id="@+id/Canvas"
    android:layout_gravity="top">

</FrameLayout>
...

和图像:add.xml:

<View android:id="@+id/image" 
        android:layout_gravity="top"
        xmlns:android="http://schemas.android.com/apk/res/android"/> 

当我点击我的 compos子时,它成功地为信.增添了形象,当我触及图像时,它的反应是,像它一样,从40x40到60x60。 但是,它没有听从我的指手,也没有我 st的。

Any input is appreciated.
