構造函數ArrayAdapter <string>是undefined

Question

我想從意圖傳遞數據到一個列表視圖，但我得到「構造函數ArrayAdapter是未定義的」錯誤。 這是我的代碼：

public class Loglist extends Activity { 

public void onCreate(Bundle savedInstanceState){ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.diary_edit); 

    TextView Exe =(TextView) findViewById(R.id.txtName2); 
    Exe.setText(getIntent().getExtras().getString("extraname")); 

    populateListView1(); 

} 

     private void populateListView1(){ 



      TextView Name1; 
     Name1.setText(getIntent().getExtras().getString("extraname")); 

      ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,R.layout.loglist,Name1); 


     ListView List =(ListView) findViewById(R.id.listViewdiary); 
     List.setAdapter(adapter2); 

     } 

Answer 1

老弟，你是想在TextView一個實例來傳遞，而你應該在String[]通過。因此，申報要String一個數組來傳遞，這樣的事情：

private void populateListView1(){ 

    TextView Name1; 
    String string1 = getIntent().getExtras().getString("extraname"); 
    Name1.setText(string1); 

    String[] array = new String[]{string1}; 
    ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this, R.layout.loglist, array); 


    ListView List =(ListView) findViewById(R.id.listViewdiary); 
    List.setAdapter(adapter2); 

}
