我想将一个整数的新值从一个活动传递到另一个活动.即:
I would like to pass a new value for an integer from one Activity to another. i.e.:
活动 B 包含一个
integer[] pics = { R.drawable.1, R.drawable.2, R.drawable.3}
我希望活动 A 将新值传递给活动 B:
I would like activity A to pass a new value to activity B:
integer[] pics = { R.drawable.a, R.drawable.b, R.drawable.c}
所以通过某种方式
private void startSwitcher() {
Intent myIntent = new Intent(A.this, B.class);
startActivity(myIntent);
}
我可以设置这个整数值.
I can set this integer value.
我知道这可以通过捆绑包以某种方式完成,但我不确定如何将这些值从活动 A 传递到活动 B.
I know this can be done somehow with a bundle, but I am not sure how I could get these values passed from Activity A to Activity B.
很简单.在发送方,使用 Intent.putExtra
:
It's simple. On the sender side, use Intent.putExtra
:
Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);
在接收方,使用 Intent.getIntExtra
:
On the receiver side, use Intent.getIntExtra
:
Intent mIntent = getIntent();
int intValue = mIntent.getIntExtra("intVariableName", 0);
