Question

我在view_inflated.xml文件下有一个带有以下xml标记的简单TextView：

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:text="Inflated view"
    >
</TextView>

我想在文件activity_main.xml下声明的LinearLayout内膨胀TextView，如下所示：

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/ll1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context=".MainActivity" >

        <ListView
            android:id="@+id/listView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"           
          >

        </ListView>

    </LinearLayout>

现在为了扩大视图我试过这样：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        resource=new String[]{"Arafat","Anik","Prottoy","Progga","Prapti",
                "Oishy","Nijha","Adil","Troyee","Kushum","Manik","Shahin","Limon"
                ,"Shumon","Lipi","Lucy","Shaikot"};

        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,resource);

        lv=(ListView) findViewById(R.id.listView1);
        lv.setAdapter(adapter);
        lv.setOnItemClickListener(this);

        LayoutInflater inflater=getLayoutInflater();
        View v=inflater.inflate(R.layout.view_inflated, null);
        LinearLayout rl=(LinearLayout) findViewById(R.id.ll1);
        rl.addView(v);
    }

问题是 - 列表视图按预期显示，但TextView不显示。如何解决这个问题？

Answer 1

暂时解决你的问题，然后想出你错过了什么

android:orientation="vertical"

activity_main.xml中的

：）

做到这一点，你的问题就会得到解决。

要在顶部设置textview，请使用相对布局

替换主布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/ll1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <ListView
        android:layout_alignParentBottom="true"
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="400dp"
       android:layout_gravity="bottom" >
    </ListView>

</RelativeLayout>

在代码中输入TypeCast，然后将视图添加到此Relative Layout先前设置适配器列表中。

喜欢这个

LayoutInflater inflater = getLayoutInflater();
    View v = inflater.inflate(R.layout.view_inflated, null);
    RelativeLayout rl = (RelativeLayout) findViewById(R.id.ll1);
    rl.addView(v);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, resource);

    ListView lv = (ListView) findViewById(R.id.listView1);
    lv.setAdapter(adapter);

Answer 2

将您的虚增视图作为页脚添加到列表视图。

在setAdapter之前

 lv=(ListView) findViewById(R.id.listView1);
 LayoutInflater inflater=getLayoutInflater();
 View v=inflater.inflate(R.layout.view_inflated, null);
 lv.addFooterView(v);
 lv.setAdapter(adapter);
 lv.setOnItemClickListener(this);

Answer 3

// try this
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, R.layout.view_inflated,resource);

Answer 4

您可以使用 Section ListView
