[Android] ListView 结合SimpleAdapter使用

1-声明变量

    private ListView listView;    private SimpleAdapter simpleAdapter;    List<Map<String,Object>> valueList = new ArrayList<>();    Map<String, Object> mapRow0 = new HashMap<>();    Map<String, Object> mapRow1 = new HashMap<>();    Map<String, Object> mapRow2 = new HashMap<>();    Map<String, Object> mapRow3 = new HashMap<>();

2-Map添加映射

    mapRow0.put("view0","第1个View");    mapRow0.put("view1","第2个View");    mapRow1.put("view0","第1个View");    mapRow1.put("view1","第2个View");    mapRow2.put("view0","第1个View");    mapRow2.put("view1","第2个View");    mapRow3.put("view0","第1个View");    mapRow3.put("view1","第2个View");

3-将Map添加到List中

    valueList.add(mapRow0);    valueList.add(mapRow1);    valueList.add(mapRow2);    valueList.add(mapRow3);

4-给listView,sampleAdapter赋值，关联listView

        listView = (ListView) findViewById(R.id.listview);        SimpleAdapter = new SimpleAdapter(MainActivity.this,                valueList,                R.layout.test_layout,                new String[]{"view0","view1"},                new int[]{R.id.gg1,R.id.gg2});        listView.setAdapter(SimpleAdapter);

这里的view0与test_layout中的gg1关联，view1与test_layout中的gg2关联；

5-设置Touch事件

        listView.setOnTouchListener(new OnTouchListener(){            @Override            public boolean onTouch(View v, MotionEvent event) {                // TODO Auto-generated method stub                if(event.getAction() == MotionEvent.ACTION_DOWN)                {                    //listView.setBackgroundColor(Color.BLUE);                    Toast.makeText(MainActivity.this,                            "TOUCH.....",                            Toast.LENGTH_LONG).show();                    //startActivity(new Intent(MainActivity.this,LoginActivity.class));                    mapRow0.put("view0","第1个 Touch-Row0");                    mapRow0.put("view1","第2个 Touch-Row0");                    listView.setAdapter(simpleAdapter);                }                return false;            }        });

修改mapRow0中的值，不用重新设置适配器simpleAdapter，只用让listView重新加载适配器即可。

6-test_layout.xml编写

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent"    android:id="@+id/testlayout">    <TextView        android:text="TextView"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@+id/gg1" />    <TextView        android:text="TextView"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@+id/gg2" />LinearLayout>
