当我输入内容时,我会得到一个自动完成预测。就像我进入" Joh"时,我得到了约翰肯尼迪"。现在,如果用户点击" John F. Kennedy",则会将他带入一个活动,向他提供有关John F. Kennedy的信息。我该怎么做才能得到这个?如何使自动填充预测可以点击?
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);
}
}

你可以尝试下面的代码,
autoCompleteTextview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick (AdapterView<?> parent, View view, int position, long id) {
//... your stuff
}
})
当用户使用setOnItemSelectedListener实际选择下拉列表中的项目时,您还有一个选项来设置点击侦听器。
autoCompleteTextview.setOnSelectedListener(new OnItemClickListener() {
@Override
public void onItemSelected (AdapterView<?> parent, View view, int position, long id) {
//... your stuff
}
});
修改强>
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);
}
依旧......

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();
}
});
}
