Question

我将报警中的毫秒存储到数据库，数据库将它们全部正确存储起来，因为我测试它在单个TextView中显示它们并显示它们全部。但我的ListView只显示有8个数字的毫秒值，当有9个或更多的数字时它不会显示它们。这是我的ListView：

<?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" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="250dp" >

    </ListView>

</LinearLayout>

我用于行的我的xml：

<?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" >

    <TextView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/text1"
        android:layout_width="match_parent"        
        android:gravity="center"
        android:layout_height="45dp" />

</LinearLayout>

用于填充ListView的方法：

private void fillData() {
        // Get all of the notes from the database and create the item list
        Cursor c = DatabaseManager.getAllData();
        startManagingCursor(c);

        String[] from = new String[] { DatabaseManager.TABLE_COLUMN_TWO };
        int[] to = new int[] { R.id.text1 };

        // Now create an array adapter and set it to display using our row
        SimpleCursorAdapter notes =
            new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to);
        setListAdapter(notes);
    }

Please replace the Listview with following code. 
Its working good.
Don't fix the height of the Listview in android:layout_height
Please replace your layout xml code with the following xml.

<?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" >

 <ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>

</LinearLayout>
