Question

我正在尝试使用AutoCompleteTextView建议进行点击，并为用户带来另一项活动。如果你们中的任何人都知道如何使用AutoCompleteTextView，请前往AutoCompleteTextView or SearchDialog?

除了调用getText（）之外，还有我正在使用的内容。另外如何在我的交换机案例中定义我的意图？

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class Search extends Activity
{


    public void onCreate(Bundle savedInstanceSate)
    {
        final int autoComplete;
        super.onCreate(savedInstanceSate);
        setContentView(R.layout.searchshop);

        AutoCompleteTextView autoCompletee = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, shops);
        autoCompletee.setAdapter(adapter); 
        autoCompletee.setThreshold(1);
        autoCompletee.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) 
        {


                Intent intent;
                int index=999;
                for(int i=0;i<shops.length;i++)
                {

                    if(shops[i].equals(autoComplete.getText().toString().trim()))
                    {
                        index=i;
                        break;
                    }
                }
                switch(index)
                {
                    case 0:
                        //The constructor Intent(Search, int) is undefined
                        intent=new Intent(Search.this, R.layout.adidas);
                        startActivity(intent);
                        setContentView(R.layout.adidas);
                        break;
                    case 1:
                        //The constructor Intent(Search, int) is undefined
                        intent=new Intent(Search.this, R.layout.affin);
                        startActivity(intent);  
                        setContentView(R.layout.affin);
                        break; 
                }
            }
        });


    }
    static final String[] shops = new String[]
            {
                "Adidas", " Affin Bank", "Alam Art", "Al Amin"

            };
}

我不知道你在int上调用getText()的位置。要将int转换为String，您可以使用String.valueOf()或Integer.toString()。

你应该用另一种方式构建意图：

intent = new Intent(Search.this, YourAnotherActivityName.class);

如何在基本类型int上调用getText（）？
