如何使按鈕與Android的按鍵編程

-5

public class DrawingBrush extends Activity { 
    package com.hisham.edureka.drawingbrush; 
    import android.app.Activity; 
    import android.os.Bundle; 
    } 

    public class DrawingBrush extends Activity { 

@Override 
    public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    MyTouchEventView tv = new MyTouchEventView(this); 
    //MyTouchEventView tv2 = new MyTouchEventView(this); 
    setContentView(tv); 
    addContentView(tv.btnReset, tv.params); 

    //setContentView(tv2); 
    //addContentView(tv2.btnSave, tv2.params); 
} 

@Override 
protected void onPause() { 
    // TODO Auto-generated method stub 
    super.onPause(); 
    finish(); 
} 

    }

MyTouchEventView.java

  btnReset = new Button(context); 
    btnReset.setText("Clear");

PARAMS =新LinearLayout.LayoutParams（LayoutParams.FILL_PARENT，LayoutParams.WRAP_CONTENT） ;

btnReset.setLayoutParams(params); 

    btnReset.setOnClickListener(new View.OnClickListener() { 

     public void onClick(View v) { 
      // TODO Auto-generated method stub 

      // resets the screen 
      path.reset(); 

      // Calls the onDraw() method 
      postInvalidate(); 

     }

我怎麼能建立一個按鈕，在底部保存按鈕保存Like按鈕清晰的按鈕不是XML，但按鍵編程.. THX諮詢
