Java 如何使自动完成预测可点击？

当我输入某物时，我得到一个自动完成的预测。比如当我进入约翰，我得到了约翰·F·肯尼迪。现在，如果用户点击约翰·F·肯尼迪，他就会进入一个活动，向他提供关于约翰·F·肯尼迪的信息。我该怎么做才能得到这个？如何使自动完成预测可点击

package com.mavenmaverick.autocomplete_test;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;


public class MainActivity extends Activity {

String[] presidents= { "John F. Kennedy",
                    "Lyndon B. Johnson",
                    "Richard Nixon",
                    "Gerald Ford",
                    "Jimmy Carter",
                    "Ronald Reagan",
                    "George H. W. Bush",
                    "Bill Clinton",
                    "George W. Bush",
                    "Barack Obama"
                    };

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

    AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.select_dialog_item, presidents);

    textView.setThreshold(3);
    textView.setAdapter(adapter);

}

}

你可以试试下面的代码

autoCompleteTextview.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick (AdapterView<?> parent, View view, int position, long id) {
        //... your stuff
    }
})

等等…

使用此代码

String[] presidents= { "John F. Kennedy",
                    "Lyndon B. Johnson",
                    "Richard Nixon",
                    "Gerald Ford",
                    "Jimmy Carter",
                    "Ronald Reagan",
                    "George H. W. Bush",
                    "Bill Clinton",
                    "George W. Bush",
                    "Barack Obama"
                    };
private AutoCompleteTextView myAutoComplete;

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

        myAutoComplete = (AutoCompleteTextView) findViewById(R.id.myautocomplete);
        myAutoComplete.addTextChangedListener(this);
        myAutoComplete.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, presidents));



myAutoComplete.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent(getBaseContext(), InforActivity.class);
                    intent.putExtra("president_name", obj.toString());
                    startActivity(intent);
                    finish();

            }
        });

}

我正在发布我的源代码。请详细说明你的答案好吗？@RahulShaw，检查我的编辑，通过上面的代码获取位置，然后检查条件，如果pos为1，则将意图传递到第二个屏幕，如果pos为2，则再次发送新屏幕，就像这样。输入“Joh”时，我得到预测“John F.Kennedy”，但选择“John F.Kennedy”时，什么都没有发生。

if(position == 1){
Intent i = new Intent (MainActivity.this, johncanedy.class);
startActivity(i);
}else if (position == 2){
Intent i = new Intent (MainActivity.this, lyndon.class);
startActivity(i);
} 

String[] presidents= { "John F. Kennedy",
                    "Lyndon B. Johnson",
                    "Richard Nixon",
                    "Gerald Ford",
                    "Jimmy Carter",
                    "Ronald Reagan",
                    "George H. W. Bush",
                    "Bill Clinton",
                    "George W. Bush",
                    "Barack Obama"
                    };
private AutoCompleteTextView myAutoComplete;

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

        myAutoComplete = (AutoCompleteTextView) findViewById(R.id.myautocomplete);
        myAutoComplete.addTextChangedListener(this);
        myAutoComplete.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, presidents));



myAutoComplete.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent(getBaseContext(), InforActivity.class);
                    intent.putExtra("president_name", obj.toString());
                    startActivity(intent);
                    finish();

            }
        });

}
