一、Android的跳转

Intent intent =newIntent(context, LoginActivity.class);

intent.putExtra("Text","Hello World");//传递参数

context.startActivity(intent);

Bundle extras = getIntent().getExtras();

String mText = extras.getString("Text");//接收参数

Log.d("你好啊","i="+mText+",大家下午好 ");//输出参数

二、ListView

1、在XML文件中布局listview

<ListView

android:id="@+id/listView_list"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:scrollingCache="false"

android:fadingEdge="none"

android:divider="@drawable/rectangle_edittext">

/*

2、定义数组来表示listView要显示，也是我们学习哪些常用的控件

*/

private static finalString[]commonFunList=newString[]{

"Everybody let us go !",

"Everybody let us go !",

};

3、对listView进行设置

listview=(ListView) findViewById(R.id.listView_list);

listview.setAdapter(newArrayAdapter(this,

android.R.layout.simple_list_item_1,

commonFunList));

//设置点击事件

listview.setOnItemClickListener(

new AdapterView.OnItemClickListener() {

@Override public void onItemClick(AdapterView adapterView, View view, int i, long l) {

Log.d("您点击了第",+ i + 1 +"个cell");

context.startActivity(intent); } } });

4、listView设置headerView

LayoutInflater lif = (LayoutInflater) getSystemService(this.LAYOUT_INFLATER_SERVICE);

View headerView = lif.inflate(R.layout.list_header,listview,false);

视图如下：
