Question

我有一个HTTP GET，它从URI接收信息。该URI适用于Google购物。

https://www.googleapis.com/shopping/search/v1/public/products?key=key&country=US&q=digital+camera&alt=atom

（离开我的钥匙）。

有没有办法可以从

更改它

q=digital+camera

用户放入EditText的任何内容？

基本上，我希望EditText改变在Google购物上搜索的内容。

第一个屏幕，带搜索查询的EditText的ProductSearchEntry：

enter image description here

ProductSearchEntry代码

public class ProductSearchEntry extends Activity{
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.productsearchentry);

    Button search = (Button) findViewById(R.id.searchButton);

    search.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent searchIntent = new Intent(getApplicationContext(), ProductSearch.class);
                startActivity(searchIntent);
        }
    });
    }
}

然后，我有第二堂课，ProductSearch，没有图片，只是这段代码：

public class ProductSearch extends Activity{
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.productsearchresults);
     EditText searchQuery = (EditText) findViewById(R.id.searchQuery);

        ProductSearchMethod test = new ProductSearchMethod();
        String entry;
        TextView httpStuff = (TextView) findViewById(R.id.httpTextView);
        try {
            entry = test.getSearchData(searchQuery.getText().toString());
            httpStuff.setText(entry);
              } catch (Exception e) {
                        e.printStackTrace();
    }
}
}

引用了ProductSearchMethod类，该类包含一个TextView，该TextView已更改为HTTP GET中收到的代码：

enter image description here

代码：

public class ProductSearchMethod {

public String getSearchData(String query) throws Exception{
    BufferedReader in = null;
    String data = null;
    try{
        HttpClient client = new DefaultHttpClient();
        URI site = new URI("https://www.googleapis.com/shopping/search/v1/public/products?key=key&country=US&q="+query.replace(" ","+")+"&alt=atom");
     HttpGet request = new HttpGet();
    request.setURI(site);
    HttpResponse response = client.execute(request);
    in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    StringBuffer sb = new StringBuffer("");
    String l = "";
    String nl = System.getProperty("line.seperator");
    while((l = in.readLine()) !=null){
        sb.append(l + nl);
    }
    in.close();
    data = sb.toString();
    return data;
    }finally{
        if (in != null){
            try{
                in.close();
                return data;
            }catch (Exception e){
                e.printStackTrace();
                }
            }
        } 
    }
}

ProductSearchMethod很棒，但它不会将文本从“加载项目”更改为网站代码。我之前有过工作，但之后我尝试编辑它搜索的内容（所有这些^），现在它没有改变。

Answer 1

在代码中进行更改，例如

public class ProductSearchEntry extends Activity{ 
protected void onCreate(Bundle savedInstanceState){ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.productsearchentry); 
    EditText etSearch = (EditText) findViewById(id of your edittext);
    Button search = (Button) findViewById(R.id.searchButton); 

    search.setOnClickListener(new View.OnClickListener() { 

        @Override 
        public void onClick(View v) { 
            //while calling intent 

            Intent searchIntent = new Intent(getApplicationContext(), ProductSearch.class); 
            searchIntent.putExtra("searchText",etSearch.getText().toString());
            startActivity(searchIntent); 
        } 
    }); 
    } 
}

和其他类似的活动，

public class ProductSearch extends Activity{     
protected void onCreate(Bundle savedInstanceState){     
    super.onCreate(savedInstanceState);     
    setContentView(R.layout.productsearchresults);     
        String searchQuery = getIntent().getStringExtra("searchText");     
        ProductSearchMethod test = new ProductSearchMethod();     
        String entry;     
        TextView httpStuff = (TextView) findViewById(R.id.httpTextView);     
        try {     
            entry = test.getSearchData(searchQuery);     
            httpStuff.setText(entry);     
              } catch (Exception e) {     
                        e.printStackTrace();     
    }     
}     
}

Answer 2

是的...更改你的getSearchData（）方法以包含一个字符串作为参数

public String getSearchData(String query) throws Exception{

然后，将该字符串插入查询URL，用“+”替换空格。您可能希望对字符串进行进一步调整，例如URL编码。

URI site = new URI("https://www.googleapis.com/shopping/search/v1/public/products?key=key&country=US&q="+query.replace(" ","+")+"&alt=atom");

在XML中，创建一个包含以下行的按钮：

android:onClick="search"

在ProductSearch活动中，添加以下方法，并将onCreate中的代码移入其中。您还需要在XML中创建EditText以进行输入。

public void search(View v)
{
    EditText searchQuery = (EditText) findViewById(R.id.searchQuery);

    ProductSearchMethod test = new ProductSearchMethod();
    String returned;
    try {
        returned = test.getSearchData(searchQuery.getText().toString());
        httpStuff.setText(returned);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();

    }
}

最后，您可能希望阅读有关运行异步任务的信息，以便查询在执行时不会冻结您的应用。

Answer 3

可能是你弄错了，但为什么不把它作为参数传递给

getSearchData() => getSearchData(string query)

然后你可以改变线

URI site = new URI("https://www.googleapis.com/shopping/search/v1/public/products?key=key&country=US&q=digital+camera&alt=atom");

到

URI site = new URI("https://www.googleapis.com/shopping/search/v1/public/products?key=key&country=US&q=+ URLEncoder.encode(query, "UTF-8")+&alt=atom");

Answer 4

签出http://androidforums.com/developer-101/528924-arduino-android-internet-garage-door-works-but-could-use-input.html我使用Asynctask在本地Arduino服务器上触发get命令。它附加了Arduino的引脚号，并根据是否需要，在URL的末尾添加一个端口号。我相信你可以用它来帮助你。

有什么方法可以根据用户输入编辑URI吗？
