Ich habe Listview mit sr, Name, Button und Timer (Textansicht) erstellt. Ich will Button muss nur anklickbar sein, nachdem der Countdown abgelaufen ist. Problem ist, dass Button klickbar ist, auch wenn Countdown läuft .Der Knopf darf nicht geklickt werden, bis die Zeit vorüber ist. Es folgt mein Code-Button innerhalb der Listview klickbar nach ein paar Sekunden
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;
}
}

Verwenden Sie view.onclicklistener so wie es ist, nur wenn der Timer läuft call view.setclickable (false) und nach dem Timer stoppt Aufruf view.setclickable (true) –
Wie man diesen Code implementieren? Kannst du mir genauen Code plz geben. – Neha
Sie klicken möchten, wenn timeDiff 0 wurde, richtig? –
