我有一個android項目，所有的源代碼沒有錯誤，但有時它給我一個力量關閉。無法添加窗口 - 令牌是您的活動運行
這裏是我的代碼：
timecompletedialog.java
public class TimeCompleteDialog implements OnClickListener {
private Activity act;
private LayoutInflater inflater;
/**UI Components*/
private Dialog dialog;
private TextView txt_msg;
private ImageButton btn_cancal;
public TimeCompleteDialog(Activity a) {
this.act=a;
inflater=LayoutInflater.from(act);
dialog=new Dialog(a);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
}
/**Attaching the dialog to custom views*/
private void buildDialog(){
View v=inflater.inflate(R.layout.time_complete_dialog,null,false);
dialog.setContentView(v);
dialog.setCancelable(false);
this.findDialogViews(v);
}
public void showDialog(){
this.buildDialog();
this.dialog.show();
}
/**Find the ids of the custom views components*/
private void findDialogViews(View view){
txt_msg=(TextView)view.findViewById(R.id.txt_time_up);
btn_cancal=(ImageButton)view.findViewById(R.id.btn_time_cancel);
btn_cancal.setOnClickListener(this);
/**Changing the state of the views*/
this.renderViews();
}
private void renderViews() {
txt_msg.setText("Sorry Time is up.\nTry Harder Next Time");
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_time_cancel:
this.dialog.dismiss();
act.finish();
break;
default:
break;
}
//Closing the dialog
}
}
在這段代碼是沒有錯誤。但我不知道什麼是錯的。

你可以給我哪來的錯誤？
您應該發佈您的代碼。 –
