我已經創建了與sr，名稱，按鈕和計時器（textview）的列表視圖。我只希望按鈕必須是倒計時結束後才能點擊。問題是即使倒計時正在進行，按鈕是可點擊的。按鈕不能點擊，直到時間結束。 以下是我的代碼 -listview裏面的按鈕幾秒後可點擊
MainActivity.java
public class MainActivity extends Activity {
Button btnnext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnnext=(Button)findViewById(R.id.btn1);
btnnext.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i=new Intent(MainActivity.this,Second.class);
startActivity(i);
}
});
}
}
Model.java
public class Model {
int sr;
String name;
long expirationTime;
public Model(int sr, String name,long expirationTime) {
this.sr = sr;
this.name = name;
this.expirationTime = expirationTime;
}
public int getSr() {
return sr;
}
public void setSr(int sr) {
this.sr = sr;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public long getExpirationTime() {
return expirationTime;
}
public void setExpirationTime(long expirationTime) {
this.expirationTime = expirationTime;
}
}
Second.java
public class Second extends Activity{
TextView txtsrno,txtflower,txtstatus,txttimer,txttimeleft;
ListView listView;
ArrayList<Model> flowerlist;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
txtsrno = (TextView) findViewById(R.id.srno);
txtflower = (TextView) findViewById(R.id.name);
txtstatus = (TextView) findViewById(R.id.buy);
txttimeleft=(TextView)findViewById(R.id.remtime);
listView = (ListView) findViewById(R.id.list);
flowerlist = new ArrayList<>();
flowerlist.add(new Model(1, "Rose",System.currentTimeMillis() + 100000));
flowerlist.add(new Model(2, "Sunflower",System.currentTimeMillis() + 10000));
flowerlist.add(new Model(3, "Lotus",System.currentTimeMillis() + 30000));
flowerlist.add(new Model(4, "Jasmine",System.currentTimeMillis() + 20000));
SecondCustom sc = new SecondCustom(this, flowerlist);
listView.setAdapter(sc);
}
}
SecondCustom.java
public class SecondCustom extends BaseAdapter {
Activity a;
ArrayList<Model> flowerlist;
private List<Viewholder> lstHolders;
long timeDiff;
private LayoutInflater lf;
private Handler mHandler = new Handler();
private Runnable updateRemainingTimeRunnable = new Runnable() {
@Override
public void run() {
synchronized (lstHolders) {
long currentTime = System.currentTimeMillis();
for (Viewholder holder : lstHolders) {
holder.updateTimeRemaining(currentTime);
}
}
}
};
public SecondCustom(Activity a, ArrayList<Model> flowerlist) {
this.a = a;
this.flowerlist = flowerlist;
lstHolders = new ArrayList<>();
startUpdateTimer();
}
private void startUpdateTimer() {
Timer tmr = new Timer();
tmr.schedule(new TimerTask() {
@Override
public void run() {
mHandler.post(updateRemainingTimeRunnable);
}
}, 1000, 1000);
}
@Override
public int getCount() {
return flowerlist.size();
}
@Override
public Object getItem(int i) {
return flowerlist.get(i);
}
@Override
public long getItemId(int i) {
return i;
}
public class Viewholder{
TextView srno,name,ltime;
Button buy;
Model mModel;
public void setData(Model item) {
mModel = item;
name.setText(item.name);
updateTimeRemaining(System.currentTimeMillis());
}
public void updateTimeRemaining(long currentTime) {
long timeDiff = mModel.expirationTime - currentTime;
if (timeDiff > 0) {
int seconds = (int) (timeDiff/1000) % 60;
int minutes = (int) ((timeDiff/(1000 * 60)) % 60);
int hours = (int) ((timeDiff/(1000 * 60 * 60)) % 24);
ltime.setText(hours +":" + minutes +":" + seconds);
} else {
ltime.setText("Buy Now!!");
}
}
}
@Override
public View getView(final int i, View convertView, ViewGroup viewGroup) {
Viewholder viewholder = null;
if (convertView == null) {
viewholder = new Viewholder();
LayoutInflater li=a.getLayoutInflater();
convertView = li.inflate(R.layout.secondcustom, viewGroup, false);
viewholder.srno = (TextView) convertView.findViewById(R.id.sr);
viewholder.name = (TextView) convertView.findViewById(R.id.flow);
viewholder.buy = (Button) convertView.findViewById(R.id.st);
viewholder.ltime = (TextView) convertView.findViewById(R.id.lefttime);
convertView.setTag(viewholder);
synchronized (lstHolders) {
lstHolders.add(viewholder);
}
}else {
viewholder = (Viewholder) convertView.getTag();
}
viewholder.setData((Model) getItem(i));
final Model model=flowerlist.get(i);
viewholder.srno.setText(valueOf(flowerlist.get(i).getSr()));
viewholder.name.setText(valueOf(flowerlist.get(i).getName()));
viewholder.ltime.setText(valueOf(flowerlist.get(i).getExpirationTime()));
if(timeDiff==0) {
viewholder.buy.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(a, "Purchased" + " " + flowerlist.get(i).getName(), Toast.LENGTH_LONG).show();
}
});
}
return convertView;
}
}
原樣使用view.onclicklistener，只是當計時器正在運行時調用view.setclickable（false）並在計時器停止後調用view.setclickable（true） –
如何實現該代碼？是否可以給我確切的代碼plz。 – Neha
你想在timeDiff變成0時點擊按鈕吧？ –
