Android如何使用checkedtextview

Question

标题不言而喻.我有几篇文章,主题,仍然没有弄清楚如何使用checkedtextview.我想要一个带有可检查项目的列表视图.在下面的代码中,我使用listview并用字符串数组填充它.但是如何将其更改为checkedtextview？

delete.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:paddingTop="4dip"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:orientation="horizontal"
     android:id="@+id/linlay0"
     android:background="@color/list_bg">
  <TextView 
        android:id="@+id/TextView00"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#D8D8D8"
        android:textColor="#424242"
        android:gravity="center_horizontal|center_vertical"
        android:textSize="20px"
        android:height="40px"
        android:textStyle="bold"
        />
     <ListView android:id="@+id/ListView01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

delete_lv.xml:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<TextView
android:id="@+id/list_content"
android:textColor="#222222"
android:gravity="center"
android:text="sample"
android:layout_margin="4dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

</LinearLayout>

Delete.java:

public class Delete extends Activity {

    ListView lv1;
    ArrayAdapter<String> adapter1;
    private String lv_items[] = { "Android", "iPhone", "BlackBerry",
                 "AndroidPeople", "J2ME", "Listview", "ArrayAdapter", "ListItem",
                 "Us", "UK", "India" };

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

TextView tv0 = (TextView)findViewById(R.id.TextView00);
tv0.setText("Deletes");

lv1 = (ListView) findViewById(R.id.ListView01);
adapter1 = new ArrayAdapter<String>(Delete.this,R.layout.list_black_text,R.id.list_content, lv_items);
lv1.setAdapter(adapter1);
adapter1.notifyDataSetChanged();

}
}

在您的xml文件中,您使用textview作为列表项.而不是那种用途CheckedTextView.您可以直接从窗口小部件面板中拖放它.你可以使用CheckedTextViewas TextView和CheckBox.以下是如何使用它的示例

   <CheckedTextView 
      xmlns:android="http://schemas.android.com/apk/res/android"     
      style="@style/NormalText"  
      android:id="@+id/checkList" 
      android:paddingLeft="20dip" 
      android:paddingRight="20dip" 
      android:paddingTop="10dip"
      android:paddingBottom="10dip" 
      android:orientation="vertical" 
      android:layout_width="fill_parent" 
      android:layout_height="?android:attr/listPreferredItemHeight"  
      android:gravity="center_vertical"  
      android:checkMark="@drawable/our_checkbox"></CheckedTextView>
