台机器人可聚焦里面排 [英] focusable row inside table android
问题描述
我有一个XML格式的滚动型其中包括一个TableLayout。 我的问题是,如果有可能我每次点击它有一个可聚焦一行。 这里是我的XML code:
i have in xml a ScrollView which includes one TableLayout. My question is if it's possible to have a focusable row every time i click on it. Here is my xml code:
<ScrollView
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:id="@+id/table2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TableRow>
<RelativeLayout
android:id="@+id/rowlayout"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="@drawable/rowbackground2" >
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/icon_code_contact"
android:padding="7dip"
android:layout_alignParentLeft="true" />
<TextView
android:id="@+id/contacts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:text="Contacts"
android:textColor="#000"
android:textSize="18dip"
android:layout_toRightOf="@id/icon"
android:paddingTop="10dip" />
</RelativeLayout>
</TableRow>
<TableRow>
<Button
android:id="@+id/contacts_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/contact_button" />
</TableRow>
我已经尝试了可聚焦=真和focusableInTouchMode =真但是什么都没有发生。
I have already tried the "focusable="true"" and "focusableInTouchMode="true"" but nothing happened..
在此先感谢
推荐答案
如果你是问如何让表表现得像ListView中,我做了以下内容:
If you are asking about how to make table to behave like ListView, I did the following:
在XML文件,定义布局我的活动,我定义的表:
In xml-file, which defines layout for my Activity, I defined the table:
<ScrollView
android:layout_height="wrap_content"
android:layout_width="fill_parent" >
<TableLayout
android:id="@+id/my_table"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:stretchColumns="1"
android:shrinkColumns="1"/>
</ScrollView>
于是,我写了单独的 table_row_item.xml
文件与表行布局:
<?xml version="1.0" encoding="UTF-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:focusable="true"
android:focusableInTouchMode="false"
android:clickable="true"
android:background="@android:drawable/list_selector_background">
<TextView
android:id="@+id/cell_1"
...
/>
...
<TextView
android:id="@+id/cell_N"
...
/>
</TableRow>
在活动我宣布过程将行添加到我的表:
In Activity I declared procedure to add a row to my table:
private void addTableRow() {
final TableLayout table = (TableLayout) findViewById(R.id.my_table);
final TableRow tr = (TableRow) getLayoutInflater().inflate(R.layout.table_row_item, null);
TextView tv;
// Fill out our cells
tv = (TextView) tr.findViewById(R.id.cell_1);
tv.setText(...);
...
tv = (TextView) tr.findViewById(R.id.cell_N);
tv.setText(...);
table.addView(tr);
// Draw separator
tv = new TextView(this);
tv.setBackgroundColor(Color.parseColor("#80808080"));
tv.setHeight(/*height of separaor line. 2dip will be enough*/);
table.addView(tv);
// If you use context menu it should be registered for each table row
registerForContextMenu(tr);
}
