Android:通过微调器可以延迟消息
用户从4个选项中选择延迟在微调器中的时间(例如,15、30、60秒或无延迟),然后当他单击发送按钮时,延迟将在消息真正发送之前生效,然后当消息发送时,将有一个祝酒词通知用户消息已发送 问题是,如何在微调器上实现延迟?它会被选中吗?那就推迟到那里?还是别的什么 代码如下:Android:通过微调器可以延迟消息,android,spinner,delay,Android,Spinner,Delay,用户从4个选项中选择延迟在微调器中的时间(例如,15、30、60秒或无延迟),然后当他单击发送按钮时,延迟将在消息真正发送之前生效,然后当消息发送时,将有一个祝酒词通知用户消息已发送 问题是,如何在微调器上实现延迟?它会被选中吗?那就推迟到那里?还是别的什么 代码如下: public class KAHTextApp extends Activity { Button btnRecipient; Button btnSend; EditText editTextRecip

}
editTextRecipient.setText(sb.toString());
}
}
打破
}
btnSend.setOnClickListener(新视图.OnClickListener(){
公共void onClick(视图v){
字符串phoneNo=editTextRecipient.getText().toString();
String message=editTextNewMessage.getText().toString();
if(phoneNo.length()>0&&message.length()>0)
Toast.makeText(getBaseContext(),
“消息已发送!”,
吐司。长度(短)。show();
/*发送短信(电话号码,信息);*/
其他的
Toast.makeText(getBaseContext(),
“请同时输入电话号码和信息。”,
吐司。长度(短)。show();
}
});
}
这是微调器的代码:
public class TimeDelay implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
Toast.makeText(parent.getContext(), "The delay is " +
parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
// Do nothing.
}
}
公共类延时实现了MSelectedListener{
已选择公共无效项(AdapterView父项,
视图,内部位置,长id){
Toast.makeText(parent.getContext(),“延迟为”+
parent.getItemAtPosition(pos.toString(),Toast.LENGTH_LONG.show();
}
未选择公共无效(AdapterView父级){
//什么也不做。
}
}
使用计时器(处理程序)进行延迟,意味着在其中编写发送和发送消息的代码,并根据延迟时间调用该函数(从微调器中选择),只需从微调器中选择一个值。使用该值调用函数(延迟)
这就是函数
private Runnable checkFunction(){
tt = new TimerTask() {
public void run() {
handler.postDelayed(checkFunction(),1000);
//// write code depending on your requirement..
}
};
return tt;
}
