我的活动中有一个倒数计时器。
当用户回答纠正时，它将加载带有剩余时间的相同活动。
但倒计时结束时，第二个活动加载循环。
这是我的ArcadeActivty代码：
public class ArcadeActivity extends Activity {
final Context context = this;
ImageView image;
String icon_game;
String[] ar;
String name;
String imge;
String desc;
String clue;
int clue_status=0;
int gid = 0;
int level = 0;
long seconds;
final TestAdapter mDbHelper = new TestAdapter(this);
int coin = 0;
private Button btn_clue;
private Button btn_skip;
private TextView txt_coins;
private View view;
private MediaPlayer mp = null;
private TextView lbl_timer;
private CountDownTimer countDownTimer;
long currentTime;
int score;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_arcade);
getActionBar().setDisplayHomeAsUpEnabled(true);
Bundle extras = getIntent().getExtras();
if(extras !=null) {
currentTime = extras.getLong("timeCode");
score = extras.getInt("myScore");
} else {
currentTime = 180000;
}
startTimer();
final Button btn_submit = (Button) findViewById(R.id.btn_submit);
btn_clue = (Button) findViewById(R.id.btn_clue);
btn_skip = (Button) findViewById(R.id.btn_skip);
lbl_timer = (TextView) findViewById(R.id.lbl_timer);
final EditText txt_answer = (EditText) findViewById(R.id.txt_answer);
ImageView img = (ImageView) findViewById(R.id.img_clue);
mDbHelper.createDatabase();
mDbHelper.open();
Cursor testdata = mDbHelper.getArcade();
name = Utility.GetColumnValue(testdata, "name");
imge = Utility.GetColumnValue(testdata, "image");
clue = Utility.GetColumnValue(testdata, "clue");
clue_status = Integer.parseInt(Utility.GetColumnValue(testdata, "clue_status"));
System.out.println(clue_status);
level = Integer.parseInt(Utility.GetColumnValue(testdata, "level_order"));
desc = Utility.GetColumnValue(testdata, "description");
gid = Integer.parseInt(Utility.GetColumnValue(testdata, "_id"));
int id = getResources().getIdentifier("com.iamnards.gameapp:drawable/" + imge, null, null);
img.setImageResource(id);
//lbl_level.setText("Level "+level);
btn_submit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (name.toLowerCase().contains(txt_answer.getText().toString().toLowerCase()) && txt_answer.getText().toString().trim().length() > 0) {
//playSound(R.raw.complete);
Toast.makeText(getApplicationContext(), "Perfect! ", Toast.LENGTH_SHORT).show();
//load_correct_details(imge,name,desc);
mDbHelper.updateArcadeStatus(gid);
mDbHelper.close();
score = score+10;
Intent i = new Intent(ArcadeActivity.this, ArcadeActivity.class);
i.putExtra("timeCode", currentTime);
i.putExtra("myScore", score);
startActivity(i);
} else {
//playSound(R.raw.error);
Toast.makeText(getApplicationContext(), "Are you serious?", Toast.LENGTH_SHORT).show();
}
}
});
btn_skip.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(ArcadeActivity.this, ArcadeActivity.class);
i.putExtra("timeCode", currentTime);
i.putExtra("myScore", score);
startActivity(i);
}
});
}
void startTimer() {
countDownTimer = new CountDownTimer(currentTime, 1000) {
// 500 means, onTick function will be called at every 500
// milliseconds
@Override
public void onTick(long leftTimeInMilliseconds) {
seconds = leftTimeInMilliseconds / 1000;
currentTime = leftTimeInMilliseconds;
lbl_timer.setText(String.format("%02d", seconds / 60)
+ ":" + String.format("%02d", seconds % 60));
}
@Override
public void onFinish() {
// this function will be called when the timecount is finished
if(currentTime<1717){
Toast.makeText(getApplicationContext(), "TIMES UP! "+currentTime, Toast.LENGTH_SHORT).show();
Intent i = new Intent(ArcadeActivity.this, ScoreActivity.class);
i.putExtra("myScore", score);
startActivity(i);
finish();
}
}
}.start();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_arcade, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
mDbHelper.close();
return true;
}
return super.onOptionsItemSelected(item);
}
public void load_clue(View v){
//handle the click here
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set title
alertDialogBuilder.setTitle("Clue:");
// set dialog message
alertDialogBuilder
.setMessage(clue)
.setCancelable(false)
.setPositiveButton("OK",new DialogInterface.OnClickListener() {
private TextView txt_coins;
public void onClick(DialogInterface dialog,int id) {
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
}
ScoresActivity代码：
public class ScoreActivity extends Activity {
final TestAdapter mDbHelper = new TestAdapter(this);
private TextView lbl_score;
int score;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_score);
Bundle extras = getIntent().getExtras();
score = extras.getInt("myScore");
lbl_score = (TextView) findViewById(R.id.lbl_score);
final EditText txt_name = (EditText) findViewById(R.id.txt_name_score);
final Button btn_save = (Button) findViewById(R.id.btn_save);
lbl_score.setText("Your score is: "+score);
mDbHelper.createDatabase();
mDbHelper.open();
btn_save.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if(isEmpty(txt_name)){
if(isEmpty(txt_name)){
Toast.makeText(getApplicationContext(), "Name must not empty. ", Toast.LENGTH_SHORT).show();
}
} else {
mDbHelper.insertScore(txt_name.getText().toString(), score);
mDbHelper.close();
Intent myIntent = new Intent(v.getContext(), ScoresActivity.class);
startActivityForResult(myIntent, 0);
}
}
});
}
private boolean isEmpty(EditText etText) {
return etText.getText().toString().trim().length() == 0;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_arcade, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
mDbHelper.close();
return true;
}
return super.onOptionsItemSelected(item);
}
}
答案 0 :(得分：0)
您已启动计时器但未停止计时器。计时器启动后，您需要取消倒计时。在onFinish（）
中添加else部分void startTimer() {
countDownTimer = new CountDownTimer(currentTime, 1000) {
// 500 means, onTick function will be called at every 500
// milliseconds
@Override
public void onTick(long leftTimeInMilliseconds) {
seconds = leftTimeInMilliseconds / 1000;
currentTime = leftTimeInMilliseconds;
lbl_timer.setText(String.format("%02d", seconds / 60)
+ ":" + String.format("%02d", seconds % 60));
}
@Override
public void onFinish() {
// this function will be called when the timecount is finished
if(currentTime<1717){
Toast.makeText(getApplicationContext(), "TIMES UP! "+currentTime, Toast.LENGTH_SHORT).show();
Intent i = new Intent(ArcadeActivity.this, ScoreActivity.class);
i.putExtra("myScore", score);
startActivity(i);
finish();
} else{
//Added else block
this.cancel();
}
}
}.start();
}
尚未测试过。但是你得到了问题所在。
