布局文件：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >
        <Button 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="添加TextView控件"
            android:onClick="add"
            android:id="@+id/btn_add"
            android:layout_gravity="center_horizontal"/>
        <ScrollView 
            
            android:layout_width="fill_parent"
            android:layout_height="60dp"
            android:background="@android:color/holo_blue_light">
            <LinearLayout 
                android:id="@+id/sc"
                android:layout_width="wrap_content"
            	android:layout_height="wrap_content"
            	android:orientation="vertical">
      
            </LinearLayout>
          
        </ScrollView>
    
    </LinearLayout>

添加事件：

public class TestActivity extends Activity {
    	TextView tvNum1 = null;
    	private int inum = 0;
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		this.setContentView(R.layout.scrollview_layout);
    		Button btn = (Button) this.findViewById(R.id.btn_add);
    		btn.setOnClickListener(new OnClickListener(){
    
    			@Override
    			public void onClick(View v) {
    				btn_add();
    			}
    			
    		});
    		//setClick();
    	}
    	
    	private void btn_add(){
    		LinearLayout sc = (LinearLayout) this.findViewById(R.id.sc);
    		final TextView tvNum = new TextView(this);
    		tvNum.setText("月季度喝茶" + inum++);
    		tvNum.setTextColor(Color.WHITE);
    		tvNum.setTextSize(20f);
    	<span style="color:#ff0000;">	tvNum.setOnClickListener(new OnClickListener(){
    			@Override
    			public void onClick(View v) {
    				Toast.makeText(TestActivity.this, tvNum.getText(), 0).show();
    			}
    		});</span>
    		sc.addView(tvNum);
    	}
    }
