我有两个按钮。
Button1
转到A然后C
Button2
去A然后B,最后是C.
这些活动之间传递了价值观。我现在遇到的问题是如何检查它们是否是从B到C的数据传递,或者只是从A到C,所以我可以为它们设置不同的条件。
活动A
btnNext.setOnClickListener(new View.OnClickListener() { //if button1 is clicked
@Override
public void onClick(View v) {
Intent intent=new Intent(getApplicationContext(),C.class); //pass spinner value and date to next class
Name = name.getSelectedItem().toString();
Weather = weather.getSelectedItem().toString();
Status=status.getSelectedItem().toString();
intent.putExtra("Name",Name);
intent.putExtra("Weather",Weather);
intent.putExtra("Status",Status);
intent.putExtra("date2",date2);
startActivity(intent);
}
});
btnForce.setOnClickListener(new View.OnClickListener() { // if button2 clicked
@Override
public void onClick(View v) {
Intent intent=new Intent(getApplicationContext(),B.class);
Name = name.getSelectedItem().toString();
Weather = weather.getSelectedItem().toString();
Status=status.getSelectedItem().toString();
intent.putExtra("Name",Name);
intent.putExtra("Weather",Weather);
intent.putExtra("Status",Status);
intent.putExtra("date2",date2);
startActivity(intent);
}
});
活动B
goDetails.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) { // if next button is clicked
Intent intent = new Intent(getApplicationContext(), C.class);
sub = SubContractors.getText().toString();
noP = NoPerson.getText().toString();
noH=NoHours.getText().toString();
intent.putExtra("sub",sub);
intent.putExtra("noP",noP);
intent.putExtra("noH",noH);
intent.putExtra("name",name);
intent.putExtra("weather",weather);
intent.putExtra("status",status);
intent.putExtra("date",date);
startActivity(intent);
}
});
}
活动c
name = getIntent().getExtras().getString("Name"); // receive name from Information
weather = getIntent().getExtras().getString("Weather"); //receive weather
date = getIntent().getExtras().getString("date2"); //receive date
status = getIntent().getExtras().getString("Status"); // receive status
如果有数据来自B,我该怎么写?
答案 0 :(得分:1)
您需要传递一些值才能知道来电的来源。 您可以使用示例ρяσѕρєяK给您。或者更好的喷射试试
startActivityForResult(_new,REQUEST_CODE);
然后
getIntent()。的getAction()
