如何在android中的另一個項目中使用項目作爲庫api？

我使用的Android，在這裏我使用了一些方法來generateviews片段的SPLITVIEW項目，定義拆分和設置背景顏色的方法的寬度，這裏是我的Java代碼：如何在android中的另一個項目中使用項目作爲庫api？

public class SplitviewActivity extends FragmentActivity implements 
     Left.OnButtonClickListener { 

    LinearLayout LEFT, RIGHT, leftfragmentln, rightfragmentln; 
    Right rightFr; 
    Left leftFr; 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //reduced the Gray Bar 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 


     setContentView(R.layout.main); 
     // initializes the objects 
     initializer(); 

     // sets the size of the two sides, give the ration here 
     setSize(20, 80); 
     // sets the colour of the two sides 
     setColor(Color.BLUE, Color.RED); 

    } 

    public void initializer() { 
     LEFT = (LinearLayout) findViewById(R.id.lnLeft); 
     RIGHT = (LinearLayout) findViewById(R.id.lnRight); 
     leftfragmentln = (LinearLayout) findViewById(R.id.lnLeftFragment); 
     rightfragmentln = (LinearLayout) findViewById(R.id.lnRightFragment); 
     rightFr = (Right) getSupportFragmentManager().findFragmentById(
       R.id.view_right); 
     leftFr = (Left) getSupportFragmentManager().findFragmentById(
       R.id.view_left); 

    } 

    public void setColor(int leftColor, int rightColor) { 

     // for landscape mode 
     if ((rightFr != null) && rightFr.isInLayout() && (leftFr != null) 
       && leftFr.isInLayout()) { 

      LEFT.setBackgroundColor(leftColor); 
      RIGHT.setBackgroundColor(rightColor); 
     } else { 
      // for portrait mode 
      RIGHT.setBackgroundColor(rightColor); 

     } 

    } 

    public void setSize(float leftsize, float rightsize) { 

     // for landscape mode 
     if ((rightFr != null) && rightFr.isInLayout() && (leftFr != null) 
       && leftFr.isInLayout()) { 

      android.widget.LinearLayout.LayoutParams par1 = (LayoutParams) LEFT 
        .getLayoutParams(); 

      android.widget.LinearLayout.LayoutParams par2 = (LayoutParams) RIGHT 
        .getLayoutParams(); 
      par1.weight = rightsize; 
      par2.weight = leftsize; 

     } 

    } 

    // a method to add view in a blank xml programatically 
    public void setView(View leftView, View rightView) { 
     if ((rightFr != null) && rightFr.isInLayout() && (leftFr != null) 
       && leftFr.isInLayout()) { 
      leftfragmentln.addView(leftView); 
      rightfragmentln.addView(rightView); 
     } else { 

      rightfragmentln.addView(rightView); 

     } 
    } 

    @Override 
    public void onClickButton(String s) { 

     if ((rightFr != null) && rightFr.isInLayout()) { 
      rightFr.setText(s); 
     } else { 
      Intent intent = new Intent(this, RightActivity.class); 
      intent.putExtra("value", s); 
      startActivity(intent); 
     } 

    } 
}

現在我想要將此代碼用作另一個項目中的庫，並且只想調用這些方法來生成視圖，請定義寬度和setbackground顏色。我嘗試過不同的方式，但沒有什麼能夠解決我的問題。任何人都可以用一個簡單的例子來幫助我嗎？
