Question

你可以告诉我如何在我的应用中添加标题吗？

有人可以指导我如何做到这一点吗？

这是此Webside的代码。

enter code here

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<!-- Editext for Search -->
<EditText android:id="@+id/inputSearch"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="Search products.."
    android:inputType="textVisiblePassword"/>

<!-- List View -->
<ListView
    android:id="@+id/list_view"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

</LinearLayout>

enter code here


<?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" >

<!-- Single ListItem -->

<!-- Product Name -->
<TextView android:id="@+id/product_name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="10dip"
    android:textSize="16dip"
    android:textStyle="bold"/>    

</LinearLayout>

在这里输入代码

 public class MainActivity extends Activity {

// List view
private ListView lv;

// Listview Adapter
ArrayAdapter<String> adapter;

// Search EditText
EditText inputSearch;


// ArrayList for Listview
ArrayList<HashMap<String, String>> productList;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Listview Data
    String products[] = {"Dell Inspiron", "HTC One X", "HTC Wildfire S", "HTC Sense", "HTC Sensation XE",
                            "iPhone 4S", "Samsung Galaxy Note 800",
                            "Samsung Galaxy S3", "MacBook Air", "Mac Mini", "MacBook Pro"};

    lv = (ListView) findViewById(R.id.list_view);
    inputSearch = (EditText) findViewById(R.id.inputSearch);

    // Adding items to listview
    adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name, products);
    lv.setAdapter(adapter);

    /**
     * Enabling Search Filter
     * */
    inputSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
            // When user changed the Text
            MainActivity.this.adapter.getFilter().filter(cs);   
        }

        @Override
        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                int arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub                          
        }
    });
}

}

Answer 1

在ListView使用方法addHeaderView(View v)

上

View header = getLayoutInflater().inflate(R.layout.header, null);
lV.addHeaderView(header)

R.layout.header是包含标题布局的资源。

请将来google或stackoverflow上的搜索功能，像这样的简单问题已经得到解答或者很容易在网上找到。要了解如何使用ListView我建议您参加this教程。

Answer 2

这可以通过为您的标题创建单独的布局，然后将该布局膨胀并执行addHeaderView（膨胀视图）到列表后来实现。在执行此set listview适配器之后。

Answer 3

执行以下操作，

LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, lv , false); //header is your layout in which you can add what ever view you want.
lv.addHeaderView(header, null, false);

但在设置ListView的适配器之前添加它，否则标题将不会显示。
