Toast，找不到的方法

Question

也放入一個導入 import android.widget.Toast;

String value = getIntent().getExtras().getString(VALUE); 
Context context = this; 
CharSequence text = value; 
int duration = Toast.LENGTH_LONG; 
public Toast T = Toast.makeText(context, text, duration); 
T.show(); - this is red and shows an error? does somebody knows what I did wrong? 

Answer 1

更改與此：

Toast toast = new Toast(context); 
toast.setDuration(Toast.LENGTH_SHORT); 
toast.setText(""); 
toast.show();
