将当前ItemId从RecyclerAdapter传递到其他类 [英] Pass the Current ItemId from RecyclerAdapter to Different class
本文介绍了将当前ItemId从RecyclerAdapter传递到其他类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想将Adapter的当前ItemID位置传递给另一个类，但是问题是每当我从下一个类切换位置时，它总是从零位置开始. 我已经使用getItemId来获得纸牌的位置，但是问题是每当我使用IngameWrkfunction中的位置来获取数据时，它总是从初始点而不是从当前页面获取数据.
I want to pass the current ItemID position of Adapter to another class.But the problem is whenever I toggle the position from the next class It always starts from zero position. I've used the getItemId to get the position of card but the problem is whenever I use The position in IngameWrkfunction to get the data ,it always fetch the data from the initial point not from the current page.

/*Two Ways of Putting One Animation In an activity
* 1st One
* Anim1 = AnimationUtils.loadAnimation(this, R.anim.new_animfile1);
// pop_img1.setVisibility(View.GONE);
Btn1.setOnClickListener(new View.OnClickListener() { <-----In this type you can put animation inside On Click Listener
@Override
public void onClick(View v) {
Layout1.setVisibility(LinearLayout.VISIBLE);
Anim1.setDuration(500);
Layout1.setAnimation(Anim1);
Layout1.animate();
Anim1.start();
}
});
*
*
* 2nd One
* public class MyActivity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); <-----In this type you can set another class outside the OnCreate Bundle
}
public void animate(View view){
LinearLayout dialog = (LinearLayout)findViewById(R.id.dialog);
dialog.setVisibility(LinearLayout.VISIBLE);
Animation animation = AnimationUtils.loadAnimation(this, R.anim.anim);
animation.setDuration(500);
dialog.setAnimation(animation);
dialog.animate();
animation.start();
}
}

推荐答案
通过您的实际onBindViewHolder位置
holder.cardview.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(mcontext,InGame_wrkfunction.class);
intent.putExtra("pos", position+1);
//passing data to the InGame_wrkfunction.class
intent.putExtra("MyData", (Parcelable) mData.get(position));
// start the activity
mcontext.startActivity(intent);
}
});
