带历史记录的EditText

Question

我想显示在TextView中引入的文本的历史记录。它应该是类似于在谷歌发挥搜索栏的东西：

通过我使用了Android的AutoCompleteTextView的时刻：completionThreshold =“1”，但我想不需要在建议开始前写任何文字。

任何想法??

试试这个它的做工精细：

MainActivity.java

import android.app.Activity; 
import android.app.ActionBar; 
import android.app.Fragment; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.AutoCompleteTextView; 
import android.os.Build; 

public class MainActivity extends Activity { 

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


     final String[] COUNTRIES = new String[] { 
      "Belgium", "France", "Italy", "Germany", "Spain" 
     }; 

     // In the onCreate method 
     AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1); 
     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, COUNTRIES); 
     textView.setAdapter(adapter); 
    } 
} 

activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

<AutoCompleteTextView 
    android:id="@+id/autoCompleteTextView1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:ems="10" 
    android:text="AutoCompleteTextView" > 

    <requestFocus /> 
</AutoCompleteTextView> 

</LinearLayout>
