AutoCompleteTextView+Okhttp3+ListView实现简单的网络数据搜索展示

其他 2018-11-01 17:54:05 阅读次数: 0

首先用OKHttp3获取网络上的数据，并保存到Serializeable的Bean类集合

OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(path+i)
                .build();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if(response.isSuccessful()){
                    String  str = response.body().string();
                    QBean Q = new Gson().fromJson(str,QBean.class);
                    list.addAll(Q.getData());
                    response.body().close();//关闭反应体
                    handler.sendEmptyMessage(1);//获取完网络数据 调用handler更新数据
                    Log.e("oooo",i+"");
                }

            }
        });

之后通知Handler更新数据

private  Handler handler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            initData();
            handler.removeMessages(1);;//关闭handler 防止内存泄漏
        }
    };
}
private void initData() {
        adapter = new MyAdapter(MainActivity.this,list);
        list_view_id.setAdapter(adapter);
        initData_data();
        arrayAdapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,data) ;
        auto_text_view.setAdapter(arrayAdapter);
}

在这里 AutoCompleteTextView 使用的是 数组适配 做到简单快速

之后是 实现网络数据 与 AutoCompleteTextView适配器里面的一个更新交互

       data = new ArrayList<>();
        if(list.size()<=0){
            return;
        }else {
            for (int i = 0; i < list.size(); i++) {
                String tit = list.get(i).getTitle().trim().toString();
                data.add(tit);
            }
        }

最后 实现数据传递  以及 接收收据

重点:

AutoCompleteTextView 的 OnItemSelectedListener事件没有做处理！
所以在使用这个类时，OnItemClickListener有效果，而OnItemSelectedListener没有效果的
auto_text_view.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Log.e("onItemClick",i+"");
                for (int k = 0; k < data.size(); k++) {
                    if(auto_text_view.getText().toString().equals(data.get(k))){
                        Intent intent  = new Intent(MainActivity.this,DetailsActivity.class);
                        ArrayList<QBean.DataBean> bean = new ArrayList<>();//todo 获取需要的信息
                        bean.add(list.get(k));
                        intent.putExtra("bean",bean);
                        startActivity(intent);
                        finish();
                    }
                }
            }
        });

之后 跳转 接收就可以啦

MainActivity:

public class MainActivity extends AppCompatActivity {
    private String path = "http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=";
    private AutoCompleteTextView auto_text_view;
    private ListView list_view_id;
    private ArrayList<QBean.DataBean> list = new ArrayList<>();
    ArrayList<String> data;
    private MyAdapter adapter;
    private ArrayAdapter<String> arrayAdapter;
    private  Handler handler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            initData();
            handler.removeMessages(1);//关闭handler 防止内存泄漏
        }
    };
    private Button but_id;

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

        for (int i = 1; i < 17; i++) {
           getData(i);
        }
        but_id.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(list.isEmpty()){
                    Toast.makeText(MainActivity.this, "网络异常!请稍后重试...", Toast.LENGTH_SHORT).show();
                    return;
                }else{
                    arrayAdapter.notifyDataSetChanged();
                    adapter.notifyDataSetChanged();
                }
            }
        });
        auto_text_view.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Log.e("onItemClick",i+"");
                for (int k = 0; k < data.size(); k++) {
                    if(auto_text_view.getText().toString().equals(data.get(k))){
                        Intent intent  = new Intent(MainActivity.this,DetailsActivity.class);
                        ArrayList<QBean.DataBean> bean = new ArrayList<>();//todo 获取需要的信息
                        bean.add(list.get(k));
                        intent.putExtra("bean",bean);
                        startActivity(intent);
                        finish();
                    }
                }
            }
        });
    }

    private void initData_data() {
        data = new ArrayList<>();
        if(list.size()<=0){
            return;
        }else {
            for (int i = 0; i < list.size(); i++) {
                String tit = list.get(i).getTitle().trim().toString();
                data.add(tit);
            }
        }
        Log.e("aaa",data.toString());
    }
    private void initData() {
        adapter = new MyAdapter(MainActivity.this,list);
        list_view_id.setAdapter(adapter);
        initData_data();
        arrayAdapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,data) ;
        auto_text_view.setAdapter(arrayAdapter);
    }

    private void getData(final int i) {
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(path+i)
                .build();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if(response.isSuccessful()){
                    String  str = response.body().string();
                    QBean Q = new Gson().fromJson(str,QBean.class);
                    list.addAll(Q.getData());
                    response.body().close();//关闭反应体
                    handler.sendEmptyMessage(1);//获取完网络数据 调用handler更新数据
                    Log.e("oooo",i+"");
                }

            }
        });
    }
    private void initView() {

        auto_text_view = (AutoCompleteTextView) findViewById(R.id.auto_text_view);
        list_view_id = (ListView) findViewById(R.id.list_view_id);
        but_id = (Button) findViewById(R.id.but_id);
    }
}

DetailsActivity:
private ImageView image_id;
    private TextView titles;
    private TextView more_id;
    String img_url,title,food_str,collect_num;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_details);
        initView();
        ArrayList<QBean.DataBean> data = (ArrayList<QBean.DataBean>) getIntent().getSerializableExtra("bean");
        //接收信息
        img_url = data.get(0).getPic();//获取对应信息
        title = data.get(0).getTitle();
        food_str = data.get(0).getFood_str();
        collect_num = data.get(0).getCollect_num();

        Picasso.with(this).load(img_url).into(image_id);
        titles.setText(title);
        more_id.setText("价格:¥"+collect_num+"\n\n"+"配料:"+food_str);
    }

    private void initView() {

        titles = (TextView) findViewById(R.id.title);
        more_id = (TextView) findViewById(R.id.more_id);
    }
