我有一个TextView
id android:id="@+id/yazi"
,我有一个内置的按钮android:OnClick="gonderB"
我可以编译这段代码:
package com.seri.bir;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends Activity {
Bilmez b;
TextView t;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
b = new Bilmez();
t = (TextView) findViewById(R.id.yazi);
}
public void gonderB (View v,TextView t,Bilmez b){
String s = " ..."+this;
b.yaziYaz(v,s,t);
}
}
class Bilmez {
public void yaziYaz(View v,String s,TextView t){
t.setText(s);
}
}
但是我有一个错误。我可以setText
在另一个班级吗?
