我正在使用SoundCloud API创建一个应用程序,并尝试附加用户输入的字符串值,但在界面上显示为null,该如何将其附加到URL中?
MainActivity.java
b.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View p1)
{
// TODO: Implement this method
search = et.getText().toString();
Log.d("search",search);
Intent i = new Intent(MainActivity.this, SoundCloud.class);
i.putExtra("mysearch", search);
startActivity(i);
Log.d("CustomUrl",SCService.CustomUrl);
Toast.makeText(MainActivity.this,""+SCService.CustomUrl,Toast.LENGTH_SHORT).show();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Config.API_URL)
.addConverterFactory(GsonConverterFactory.create()).build();
SCService Scservice = retrofit.create(SCService.class);
Call<Track> call = Scservice.getTrack(search);
call.enqueue(new Callback<Track>(){
@Override
public void onResponse(Call<Track> call, Response<Track> response)
{
// TODO: Implement this method
if (response.isSuccessful())
{
Track track = response.body();
streamUrl = track.getStreamUrl();
trackname = track.getTitle();
Log.e("track", track.getTitle());
Toast.makeText(MainActivity.this, trackname, Toast.LENGTH_SHORT).show();
Toast.makeText(MainActivity.this, "url" + streamUrl, Toast.LENGTH_SHORT).show();
//addToList(trackname);
}
}
@Override
public void onFailure(Call<Track> p1, Throwable p2)
{
// TODO: Implement this method
Toast.makeText(MainActivity.this,"error"+p2.getMessage(),Toast.LENGTH_SHORT).show();
//showMessage("Network Error: " + p2.getMessage());
Log.d("error", p2.getMessage());
}
});
}
});
ScService.java
public interface SCService
{
public String CustomUrl = Config.API_URL+"/resolve.json?url="+SoundCloud.SCURL+"&client_id="+Config.CLIENT_ID;
@GET("/resolve.json?url={SCURL}"+"&client_id="+Config.CLIENT_ID)
Call<Track> getTrack(@Path("SCURL")String SCURL);
}
搜索的字符串在我的SoundCloud.java类中。
SCURL = receivedmsg.getString("mysearch");
Log.d("intentdata",SCURL);
tv.setText("Search Results for " + SCURL);
我希望将SCURL字符串附加到GET参数中,但它显示SCURL的值为空,我该如何实现?
更新:我已经按照上面的代码进行了更改,但是出现了这个错误。
