我想创建选项卡式应用程序.
一切都很好,但是当我创建标签时.标签之间的空间太大了.
我想删除这个填充或边距,但我不知道我该怎么做.
有什么建议吗?

这是我的代码:
- public class MainActivity extends Activity {
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_main);
- TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);
- tabHost.setup();
- final TabWidget tabWidget = tabHost.getTabWidget();
- final FrameLayout tabContent = tabHost.getTabContentView();
- tabHost.getTabWidget().setDividerDrawable(R.drawable.empty);
- // Get the original tab textviews and remove them from the viewgroup.
- TextView[] originalTextViews = new TextView[tabWidget.getTabCount()];
- for (int index = 0; index < tabWidget.getTabCount(); index++) {
- originalTextViews[index] = (TextView) tabWidget.getChildTabViewAt(index);
- }
- tabWidget.removeAllViews();
- // Ensure that all tab content childs are not visible at startup.
- for (int index = 0; index < tabContent.getChildCount(); index++) {
- tabContent.getChildAt(index).setVisibility(View.GONE);
- }
- // Create the tabspec based on the textview childs in the xml file.
- // Or create simple tabspec instances in any other way...
- for (int index = 0; index < originalTextViews.length; index++) {
- final TextView tabWidgetTextView = originalTextViews[index];
- final View tabContentView = tabContent.getChildAt(index);
- TabSpec tabSpec = tabHost.newTabSpec((String) tabWidgetTextView.getTag());
- tabSpec.setContent(new TabHost.TabContentFactory() {
- @Override
- public View createTabContent(String tag) {
- return tabContentView;
- }
- });
- if (tabWidgetTextView.getBackground() == null) {
- tabSpec.setIndicator(tabWidgetTextView.getText());
- } else {
- tabSpec.setIndicator(tabWidgetTextView.getText(),tabWidgetTextView.getBackground());
- }
- tabHost.addTab(tabSpec);
- }
- tabHost.getTabWidget().setDividerDrawable(R.drawable.empty);
- if (Integer.parseInt(Build.VERSION.SDK) >= Build.VERSION_CODES.HONEYCOMB) {
- tabHost.getTabWidget().setShowDividers(LinearLayout.SHOW_DIVIDER_NONE);
- }
- // tabHost.setCurrentTab(0);
- }
- }
解决方法
如果你看一下Tablayout的基本风格:
- <style name="Base.Widget.Design.TabLayout" parent="android:Widget">
- <item name="tabMaxWidth">@dimen/tab_max_width</item>
- <item name="tabIndicatorColor">?attr/colorAccent</item>
- <item name="tabIndicatorHeight">2dp</item>
- <item name="tabPaddingStart">12dp</item>
- <item name="tabPaddingEnd">12dp</item>
- <item name="tabBackground">?attr/selectableItemBackground</item>
- <item name="tabTextAppearance">@style/TextAppearance.Design.Tab</item>
- <item name="tabSelectedTextColor">?android:textColorPrimary</item>
- </style>
你看到这两行
- <item name="tabPaddingStart">12dp</item>
- <item name="tabPaddingEnd">12dp</item>
所以只需为你的Tablayout创建一个样式,如下所示:
- <style name="tab_bar">
- <item name="android:layout_width">match_parent</item>
- <item name="android:layout_height">65dp</item>
- <item name="android:background">@color/backgroundColor</item>
- <item name="android:tabStripEnabled">false</item>
- <item name="tabPaddingStart">0dp</item>
- <item name="tabPaddingEnd">0dp</item>
- </style>
并使用风格:
- <android.support.design.widget.TabLayout android:id="@+id/tabs"
- app:tabGravity="fill"
- app:tabMode="fixed"
- style="@style/tab_bar"/>
