在單擊Android中的編輯文本時顯示微調？

Question

當用戶點擊editText字段我需要從該用戶顯示微調（動態）選擇我需要設置文本編輯文本的任何項目。如何做到這一點？

Answer 1

您應該使用AutoCompleteTextView。

Answer 2

public class Main extends Activity implements OnClickListener{ 

TextView textview_countries; 

private String[] countries_list={"Philippines","Japan","Australia"}; 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    textview_countries=(TextView) findViewById(R.id.txtview_countries); 
    textview_countries.setInputType(InputType.TYPE_NULL); //To hide the softkeyboard 


    final ArrayAdapter<String> spinner_countries = new ArrayAdapter<String>(Main.this,android.R.layout.simple_spinner_dropdown_item, countries_list); 

    textview_countries.setOnClickListener(new OnClickListener() { 

     public void onClick(View v) { 
      new AlertDialog.Builder(Main.this) 
        .setTitle("Select Countries") 
        .setAdapter(spinner_countries, new DialogInterface.OnClickListener() { 

        public void onClick(DialogInterface dialog, int which) { 
         textview_countries.setText(countries_list[which].toString()); 
         dialog.dismiss(); 
        } 
        }).create().show(); 
     } 
    }); 
}
