SearchView一个类似百度搜索框关键字搜索效果的实现

1.先来看一下效果吧：

 

还有

 

 

2.实现贼简单，看代码

MainActivity:

 

public class MainActivity extends AppCompatActivity {

    private SearchView searchView;
    private RecyclerView recy;
    private ArrayList<String> findList=new ArrayList<>();
    private ArrayList<String> list=new ArrayList<>();
    private listViewAdapter findAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        initData();
    }

    private void initData() {
        list.add("我是程序员");
        list.add("我是程序员哈哈哈");
        list.add("我是人");
        list.add("我不是人");
        list.add("lalla ");
        list.add("Ia");
        list.add("Ja");
        list.add("Ka");
        list.add("La");
        list.add("Ma");
        list.add("Na");
    }

    private void initView() {
        searchView = (SearchView) findViewById(R.id.searchEdit);
        recy = (RecyclerView) findViewById(R.id.Recy);

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

            //输入完成后，提交时触发的方法，一般情况是点击输入法中的搜索按钮才会触发，表示现在正式提交了
            public boolean onQueryTextSubmit(String query) {
                if(TextUtils.isEmpty(query)) {
                    Toast.makeText(MainActivity.this, "请输入查找内容！", Toast.LENGTH_SHORT).show();
                    recy.setAdapter(findAdapter);
                }else{
                    findList.clear();
                    for(int i = 0; i < list.size(); i++) {
                       // iconInformation information = list.get(i);
                        String s = list.get(i);
                        if(s.equals(query)) {
                            findList.add(s);
                            break;
                        }
                    }
                    if(findList.size() == 0) {
                        Toast.makeText(MainActivity.this, "查找的商品不在列表中", Toast.LENGTH_SHORT).show();
                    }else {
                        Toast.makeText(MainActivity.this, "查找成功", Toast.LENGTH_SHORT).show();
                        findAdapter = new listViewAdapter(findList);
                        recy.setAdapter(findAdapter);
                    }
                }
                return true;
            }

            //在输入时触发的方法，当字符真正显示到searchView中才触发，像是拼音，在输入法组词的时候不会触发
            public boolean onQueryTextChange(String newText) {
                if(TextUtils.isEmpty(newText)) {
                    recy.setAdapter(findAdapter);
                }
                else {
                    findList.clear();
                    for(int i = 0; i < list.size(); i++) {
                       // iconInformation information = list.get(i);
                        String s = list.get(i);
                        if(s.contains(newText)) {
                            findList.add(s);
                        }
                    }
                    recy.setLayoutManager(new LinearLayoutManager(MainActivity.this));
                    findAdapter = new listViewAdapter(findList);
                    findAdapter.notifyDataSetChanged();
                    recy.setAdapter(findAdapter);
                }
                return true;
            }
        });
    }
}

适配器 ：

public class listViewAdapter extends RecyclerView.Adapter<listViewAdapter.Holder>{
    ArrayList<String> mArray;
        private View inflate;

        public listViewAdapter(ArrayList<String> mArray) {
            this.mArray = mArray;
        }

        @Override
        public Holder onCreateViewHolder(ViewGroup parent, int viewType) {
            inflate = LayoutInflater.from(parent.getContext()).inflate(R.layout.recytext, parent, false);
            Holder holder = new Holder(inflate);
            return holder;
        }

        @Override
        public void onBindViewHolder(Holder holder, final int position) {
            holder.name.setText(mArray.get(position));
        }

        @Override
        public int getItemCount() {
            return mArray.size();
        }

        public class Holder extends RecyclerView.ViewHolder {

            private final TextView name;

            public Holder(View itemView) {
                super(itemView);
                name = itemView.findViewById(R.id.name);
            }
        }

}

 

main_xml布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">

        <android.support.v7.widget.SearchView
            android:id="@+id/searchEdit"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
        </android.support.v7.widget.SearchView>

    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="8">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/Recy"
            android:layout_width="match_parent"
            android:layout_height="match_parent"></android.support.v7.widget.RecyclerView>

    </LinearLayout>

</LinearLayout>

适配器中引用的布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/name"
        android:gravity="center"
        android:textSize="20sp"
        android:text="姓名"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <View
        android:layout_width="match_parent"
        android:background="#bbb"
        android:layout_height="0.5dp"/>
</LinearLayout>

 

 

由此可见就是这么简单，数据可以进行网络请求添加数据，也可以添加自己的死数据，看需求，

这次就分享到这了 ！！！
