我正在为 android 中的滑动标签创建演示。

添加所有必需的 java 和 Xml 文件后，应用程序正在崩溃。

使用上面的链接我创建了演示。

MainActivity.java

public class MainActivity extends AppCompatActivity {

    // Declaring Your View and Variables

    Toolbar toolbar;
    ViewPager pager;
    ViewPagerAdapter adapter;
    SlidingTabLayout tabs;
    CharSequence Titles[]={"Home","Events"};
    int Numboftabs =2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        // Creating The Toolbar and setting it as the Toolbar for the activity

        toolbar = (Toolbar) findViewById(R.id.tool_bar);
        setSupportActionBar(toolbar);


        // Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.
        adapter =  new ViewPagerAdapter(getSupportFragmentManager(),Titles,Numboftabs);

        // Assigning ViewPager View and setting the adapter
        pager = (ViewPager) findViewById(R.id.pager);
        pager.setAdapter(adapter);

        // Assiging the Sliding Tab Layout View
        tabs = (SlidingTabLayout) findViewById(R.id.tabs);
        tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width

        // Setting Custom Color for the Scroll bar indicator of the Tab View
        tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
            @Override
            public int getIndicatorColor(int position) {
                return getResources().getColor(R.color.tabsScrollColor);
            }
        });

        // Setting the ViewPager For the SlidingTabsLayout
        tabs.setViewPager(pager);



    }

Answer 1

对于您的第二个错误，将此添加到您的 style.xml

<style >
        <item name="android:windowActionBar">false</item>
</style>

Answer 2

我找到了问题的答案

Link i referred

在 Styles.xml 中添加这一行

样式.xml

<style name="NoActionBarTheme" parent="Theme.AppCompat.Light.NoActionBar">

   </style>

在清单文件中将您的主题样式更改为 NoActionBarTheme
