我将WishFriendsFamily的意向发送给WishFamily会员，在WishFriendsFamily我有listview我正在获取数据，直到这里工作正常，然后我能够想要WishFamilyMember，并在我的WishFamily会员活动中有一个按钮可以回到WishFriendsFamily，每当我回到WishFriendsFamily的listview时就变为空

答案 0 :(得分：1)
backaro.setOnClickListener中的WishFamilyMember应如下：
backaro.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(WishFamilyMember.this, WishFriendsFamily.class);
intent.putExtra("friendname",friendname );
intent.putExtra("friendimage",friendimage );
intent.putExtra("frienid",frienid );
intent.putExtra("userloginid",userloginid );
startActivity(intent);
}
});
或者你可以调用onBackPressed（）;而不是像这样发送Intent：
backaro.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onBackPressed();
}
});
我希望我能正常工作。
