如何从AutoCompleteTextView获取字符串文本？

Question

public class FareActivity extends Activity {


int fareid;
String Source;
String Dest;
AutoCompleteTextView source;
AutoCompleteTextView dest;


static final String[] SOURCE = new String[] {
      "Delhi", "Mumbai", "Agra", "Jaipur};


static final String[] DEST = new String[] {
      "Delhi", "Mumbai", "Agra", "Jaipur};




/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fare);




    dest = (AutoCompleteTextView) findViewById(R.id.acdest);
    ArrayAdapter<String> dadapter = new ArrayAdapter<String>(this, R.layout.list_item, DEST);
    dest.setAdapter(dadapter);



source = (AutoCompleteTextView) findViewById(R.id.acsource);
ArrayAdapter<String> sadapter = new ArrayAdapter<String>(this, R.layout.list_item, SOURCE);
    dest.setAdapter(sadapter);




 // Fare id calculation

     if(Source=="Delhi" && Dest=="Jaipur")
     {
         fareid=1;
     }
     else  if(Source=="Delhi" && Dest=="Agra")
     {
         fareid=2;
     }
     else  if(Source=="Delhi" && Dest=="Mumbai")
     {
         fareid=3;
     }


}

我只想将autocompletetextview'source'和autocompletetextview'dest'值存储到String变量'Source'和String Variable'Dest'.我将在我的项目中使用两个字符串变量进行进一步处理,所以请帮助我.

只需使用AutoCompleteTextView方法getText()并调用toString()它.

// Fare id calculation
Source = source.getText().toString();
Dest = dest.getText().toString();

if (Source.equals("Delhi") && Dest.equals("Jaipur")) {
    fareid=1;
}
else if (Source.equals("Delhi") && Dest.equals("Agra")) {
    fareid=2;
}
else if (Source.equals("Delhi") && Dest.equals("Mumbai")) {
    fareid=3;
}

您应该记住,用户可以在AutoCompleteTextView中输入他们想要的所有内容.如果要执行的操作,当用户选择建议的项目之一,添加OnItemSelectedListener有dest.setOnItemSelectedListener().

您调用的代码中也存在错误,dest.setAdapter(sadapter)而不是source.setAdapter(sadapter).
