所有android设备的特定图像位置

Question

I am developing an android board game in which images can be dragged. I want to put images on particular position when the game starts and position should remain same on each device. I am using Linear layout and absolute layout. I have calculated screen width and apply formula,position of image and use set X() and set Y() but still it is not working. Position changed when i run application. need help please.

his is xml layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/bk"
android:id="@+id/LLayout"
>

    <AbsoluteLayout
        android:id="@+id/absLayout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_x="0dp"
            android:layout_y="0dp"
            android:src="@drawable/dice" />
          <ImageView
            android:id="@+id/imageView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_x="0dp"
            android:layout_y="0dp"
            android:src="@drawable/dice" />

    </AbsoluteLayout>

</LinearLayout>

Here is .java: When i add values in setX() and setY() it does not display images on correct point. Moreover i want the images should keep same position even on different devices that is why i am calculating position according to screen density.

public class MoveImagesOnTouchActivity extends Activity{
    ImageView img=null;
    ImageView img2=null;

            }
        });
        aLayout.setOnTouchListener(new OnTouchListener() {

                    LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT,(int)event.getX()-img.getWidth()/2,(int)event.getY()-img.getHeight()/2);
                    img.setLayoutParams(lp);

                }

For setting image position you can use

if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB  ) {
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
    params.leftMargin = (int) 50; // use your value
    params.topMargin = (int) 50;  
    mImageView.setLayoutParams(params);
}else{
    // your setX() and setY()   
}

You need to specify for lower versions than HONEYCOMB

In My Case I am trying to set position for layout using below

     /**
     * @param Relative-Layout layout for set position
     * @param height [preous layout height
     */
    @SuppressLint("NewApi")
    public void setLayoutXY(LinearLayout linearLayout, int height) {
        // TODO Auto-generated method stub
        if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB  ) {
            // only for lower version than honeycomb
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); 
            params.topMargin = height; 
            linearLayout.setLayoutParams(params);
        }
        else{
            linearLayout.setY(height);
        }
    }
