上次写的可能有人说阅读性太差,所以改成这种编辑了
用到的工具主要是pinyin4j(compile ‘com.belerweb:pinyin4j:2.5.1’),将字符串转化成首字拼写或全拼,然后是计算关键字的方法.- 1.首先是布局界面,可根据需求变更
1. <?xml version="1.0" encoding="utf-8"?> 2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 3. xmlns:tools="http://schemas.android.com/tools" 4. android:id="@+id/activity_srearch" 5. android:orientation="vertical" 6. android:layout_width="match_parent" 7. android:layout_height="match_parent"> 8. <LinearLayout 9. android:background="@color/white" 10. android:paddingTop="@dimen/status_bar_height" 11. android:orientation="horizontal" 12. android:gravity="center_vertical" 13. android:layout_width="match_parent" 14. android:layout_height="@dimen/activity_titleHeight"> 15. <ImageView 16. android:id="@+id/iv_left" 17. android:padding="10dp" 18. android:src="@mipmap/back" 19. android:layout_width="wrap_content" 20. android:layout_height="wrap_content" /> 21. <SearchView 22. android:gravity="center_vertical" 23. android:id="@+id/search_view" 24. android:layout_width="match_parent" 25. android:layout_height="match_parent" 26. android:iconifiedByDefault="false" 27. android:imeOptions="actionSearch" 28. android:queryHint="搜索" /> 29. </LinearLayout> 30. <ListView 31. android:id="@+id/lv_search" 32. android:scrollbars="none" 33. android:layout_width="match_parent" 34. android:layout_height="match_parent"/> 35. </LinearLayout>
