我的程序中有一个名为＆＃34; button1＆＃34;的按钮。当我点击它时没有任何反应，而我希望该程序可以调用AjouteNouveauArticle类。
此外，当我在模拟器上运行应用程序时，我收到此错误：
getSlotFromBufferLocked: unknown buffer: 0xa17a7690
出了什么问题？
我的计划：
public class PageAccueil extends AppCompatActivity {
public static ArrayList< ToolType> ToolType = new ArrayList<ToolType>();//llist tol type
AQuery aq;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page_accueil);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
public void next(View view){
Intent intent1=new Intent(this,MotPasseOublier.class);
startActivity(intent1);
}}
这是我按下按钮1时要调用的第二个类：
public class AjouteNouveauArticle extends Activity {
String TempToolID;
GridView ls;

Spinner spinner ;
AQuery aq;

final Random rand = new Random();
String diceRoll =String.valueOf( rand.nextInt(7000000) + 5000);
TempToolID=EnrigistrementDonnee.UserID+ "000000"+ diceRoll ;
// initialize the gridview
fullsongpath.add(new AjouteImage("NewImage", R.drawable.cloud,null));

答案 0 :(得分：0)
您需要在PageAccueil活动的onCreate函数内初始化按钮上的单击侦听器。
Button button = (Button)findViewById(R.id.BuSaveSetting);
button.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v){
next(v);
}
});
