/**定义一StringBuffer*/
private StringBuffer mBuffer;


@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initViews();
initListeners();
}

private void initListeners() {
mListView.setOnItemSelectedListener(mLvOnItemSelectedListener);
mListView.setOnItemClickListener(mLvOnItemClickListener);
}

private void initViews() {
/**初始化mParentLinearLayout*/
mParentLinearLayout = new LinearLayout(TestActivity.this);
/**设置布局宽高*/
LinearLayout.LayoutParams mLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
/**布局排列方式*/
mParentLinearLayout.setOrientation(LinearLayout.VERTICAL);
/**背景*/
