我做了一个简单的应用程序。我已尝试从按钮对话框重新启动活动，活动已重新启动，但时间不是。
这是我的对话：
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_score_save:
if(this.saveScoreCard()){
this.dialog.dismiss();
act.finish();
}
break;
case R.id.btn_score_cancel:
this.dialog.dismiss();
act.finish();
break;
case R.id.btn_score_retry:
this.dialog.dismiss();
act.finish();
act.startActivity(new Intent(act,QuizActivity.class));
break;
case R.id.ing_btn_score_share:
if(isValidated()){
shareScore();
}else{
edt_name.setError(ERROR);
}
break;
default:
break;
}
//Closing the dialog
}
这是我的时间码：
private TextView questionTextView,timer_text,score_text;
private ImageButton option_1, option_2, option_3, option_4;
private LinearLayout layout;
private Handler handler=new Handler();
public static int timer;
private OnTimeCompleteListener timeComplete=(OnTimeCompleteListener)this;
private Runnable timerThread=new Runnable() {
@Override
public void run() {
if(timer>0){
//Time is running
timer--;
timer_text.setText("Time : "+timer);
handler.postDelayed(this, 1000);
}else{
timeComplete.onTimeFinish();
}
}
};
我试过第一个答案。
但是当我删除static中的timer时，它会在级别活动中出错。
这是我的错误级别活动
public class LevelActivity extends Activity implements OnClickListener {
public static final String INTENT_KEY="Select Level";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.level_activity_layout);
SetHeader.handleHeader(findViewById(R.id.header_txt),"Select Level");
findViewById(R.id.level_1).setOnClickListener(this);
findViewById(R.id.level_2).setOnClickListener(this);
findViewById(R.id.level_3).setOnClickListener(this);
findViewById(R.id.level_4).setOnClickListener(this);
findViewById(R.id.level_5).setOnClickListener(this);
}
@Override
public void onClick(View v) {
Intent i=new Intent(this,QuizActivity.class);
switch (v.getId()) {
case R.id.level_1:
QuizActivity.timer = 60;
QuizActivity.QUESTION_LIMIT = 10;
break;
case R.id.level_2:
QuizActivity.timer = 50;
QuizActivity.QUESTION_LIMIT = 10;
break;
case R.id.level_3:
QuizActivity.timer = 30;
QuizActivity.QUESTION_LIMIT = 10;
break;
case R.id.level_4:
QuizActivity.timer = 20;
QuizActivity.QUESTION_LIMIT = 10;
break;
case R.id.level_5:
QuizActivity.timer = 10;
QuizActivity.QUESTION_LIMIT = 10;
break;
default:
}
startActivity(i);
}
}
我认为问题在于重试按钮，但我不知道什么是错的。它必须完美地工作。活动重新启动，但时间仍然没有重新启动，我的意思是它恢复了

答案 0 :(得分：0)
只需将Timer设置为您在StartActivity之前的New Activity中所需的值，
在测验活动中
public static int LEVEL=0,timer=0; //declare this in Quiz Activity
case R.id.btn_score_retry:
this.dialog.dismiss();
act.finish();
switch (LEVEL) {
case 1:
QuizActivity.timer= 60;
break;
case 2:
QuizActivity.timer= 50;
break;
case R.id.level_3:
QuizActivity.timer=30;
break;
case R.id.level_4:
QuizActivity.timer= 20;
break;
case R.id.level_5:
QuizActivity.timer= 10;
break;
default:
}
act.startActivity(new Intent(act,QuizActivity.class));
break;
在你的等级活动以及定时器设置等级
@Override
public void onClick(View v) {
Intent i=new Intent(this,QuizActivity.class);
switch (v.getId()) {
case R.id.level_1:
QuizActivity.timer = 60;
QuizActivity.QUESTION_LIMIT = 10;
QuizActivity.LEVEL=1;
break;
case R.id.level_2:
QuizActivity.timer = 50;
QuizActivity.QUESTION_LIMIT = 10;
QuizActivity.LEVEL=2;
break;
case R.id.level_3:
QuizActivity.timer = 30;
QuizActivity.QUESTION_LIMIT = 10;
QuizActivity.LEVEL=3;
break;
case R.id.level_4:
QuizActivity.timer = 20;
QuizActivity.QUESTION_LIMIT = 10;
QuizActivity.LEVEL=4;
break;
case R.id.level_5:
QuizActivity.timer = 10;
QuizActivity.QUESTION_LIMIT = 10;
QuizActivity.LEVEL=5;
break;
default:
}
