ListView页首横幅间距太小，我可以使行更紧密吗？

Question

Right now I have a ListView that shows high scores in a database. My rows right now are very spaced out, and I'd like them to be closer. However I can't figure this out. Here's what my tables look like on the emulator:

Here's my code: Here is Leaderboard xml:

<ListView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/display_listview"
    android:layout_below="@+id/time" />

Here is Leaderboard_row xml:

<LinearLayout

    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/mathAnswer"
    android:layout_marginTop="10dp">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@color/orange"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="-----------"
        android:textSize="25sp"
        android:textColor="#000"
        android:id="@+id/lb_rank"
        android:gravity="center"
        android:layout_alignParentLeft="true" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@color/orange"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="-----------"
        android:textSize="25sp"
        android:textColor="#000"
        android:id="@+id/lb_score"
        android:gravity="center"
        android:layout_toRightOf="@id/lb_rank"/>

    <TextView
        android:layout_width="130dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@color/orange"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="-----------"
        android:textColor="#000"
        android:textSize="25sp"
        android:id="@+id/lb_time"
        android:gravity="right"
        android:layout_toRightOf="@id/lb_score"/>
</LinearLayout>

Is there something I can do to make these rows closer together?

Answer 1

your xml looks pretty messed up. you are using a lot of attributes that are only for relative layout. Try this:

<LinearLayout

    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation = "horizontal"
    android:layout_marginTop="10dp">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/orange"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="-----------"
        android:textSize="25sp"
        android:textColor="#000"
        android:id="@+id/lb_rank"
        android:gravity="center" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/orange"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="-----------"
        android:textSize="25sp"
        android:textColor="#000"
        android:id="@+id/lb_score"
        android:gravity="center"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/orange"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="-----------"
        android:textColor="#000"
        android:textSize="25sp"
        android:id="@+id/lb_time"
        android:gravity="right"/>
</LinearLayout>

Answer 2

The line - android:layout_marginTop="10dp" in Leaderboard_row Linear Layout is adding space between rows. Removing this line should place the rows one below the other with out any space between them.

And android:layout_alignParentLeft, android:layout_toRightOf are Relative Layout properties and should not be used inside Linear Layout.
