我正在尝试在我的 Android tabWidget 中使用简单的 gridView 填充字符串。我有一个带有三个选项卡的 tabHost,每个选项卡都有一个 XML 文件中描述的线性布局。我尝试在其下方设置一个按钮和网格。实现这一目标的最简单方法是什么?
当我尝试这样的事情时:
<LinearLayout
android:id="@+id/tab2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id ="@+id/downloadBtn"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="pobierz waluty"
/>
<GridView
android:id="@+id/grid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:verticalSpacing="35px"
android:horizontalSpacing="5px"
android:numColumns="auto_fit"
android:columnWidth="100px"
android:stretchMode="columnWidth"
android:gravity="center"
/>
在 Java 中:
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String[] items={"lorem", "ipsum", "dolor", "sit", "amet",
"consectetuer", "adipiscing", "elit", "morbi", "vel",
"ligula", "vitae", "arcu", "aliquet", "mollis",
"etiam", "vel", "erat", "placerat", "ante",
"porttitor", "sodales", "pellentesque", "augue", "purus"};
downloadXML = (Button)findViewById(R.id.downloadBtn);
GridView grid= (GridView)findViewById(R.id.grid);
grid.setAdapter(new ArrayAdapter<String> (this,android.R.layout.simple_list_item_1, items));
TabHost tabs = (TabHost)findViewById(R.id.tabHost);
tabs.setup();
TabHost.TabSpec spec = tabs.newTabSpec("tag1");
spec.setContent(R.id.tab1);
spec.setIndicator("kalkulator");
tabs.addTab(spec);
spec= tabs.newTabSpec("tag2");
spec.setContent(R.id.tab2);
spec.setIndicator("kurs walut");
tabs.addTab(spec);
spec=tabs.newTabSpec("tag3");
spec.setContent(R.id.tab3);
spec.setIndicator("konwerter");
tabs.addTab(spec);
}
我的第二个标签中只有按钮可见。
