如何使用 Recyclerview 中的按钮单击拨打电话

Question

我想使用 ACTION_CALL 方法。问题是当我单击第一个卡片视图的按钮时，应用程序会拨打电话号码11111111。 & 当我点击第二张卡片的按钮时，应用程序也会调用相同的号码1111111。 我想要的是当我单击它调用111111 的第一个卡片视图的按钮时 当我点击第二个卡片视图的按钮时，它调用22222222

Answer 1

这已经很老了，但我希望有人会发现这个答案很有用：

• 首先，您在按钮侦听器中对要呼叫的号码进行硬编码。因此，无论您点击什么按钮，您都是在要求它拨打 1111111。
• 您需要在 Celebrity 类中为电话号码添加一个字段。然后在您的适配器中，创建一个将在您的 MainActivity 类中实现的接口。因此，在点击一个项目（在本例中是一个卡片视图）时，您检索名人的电话号码，并将其提供给您实现的界面，您可以在该界面中呼叫名人。
• 这样做，您将检索每个名人的正确电话号码，而不是使用您当前拥有的硬编码字符串。

适配器：

public interface CardClickListener {
   onCardClicked(Celebrity celebrity);
}

主活动：

public class MainActivity extends AppCompatActivity implements ItemAdapter.CardClickListener {
......

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

........

// add the following to your onCreate method 
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(this, recyclerView, new ClickListener() {
        @Override
        public void onClick(View view, int position) {
            Celebrity celebrity = itemList.get(position);
            onCardClicked(celebrity);
        }

        @Override
        public void onLongClick(View view, int position) {

        }
    }));
.........
}

// implement your interface here
@Override
public void onCardClicked(Celebrity celebrity) {
   // don't forget to check for permissions
   Intent callIntent = new Intent(Intent.ACTION_CALL);
   callIntent.setData(Uri.parse("tel:" + celebrity.phone));
}

......

// add phone numbers to your class definitions
private void fillDummyData(ArrayList<Celebrity> celebList) {
   Celebrity celeb1 = new Celebrity();
   celeb1.setName("Johny.D");
   celeb1.setFamousMovie("Pirates  ");
   celeb1.setPhone("111111");
   celeb1.setProfilePhotoLocation("@drawable/contact1");
   celebList.add(celeb1);

   Celebrity celeb2 = new Celebrity();
   celeb2.setName("Arnold");
   celeb2.setFamousMovie("The Terminator");
   celeb2.setPhone("222222");
   celeb2.setProfilePhotoLocation("http://ia.mediaimdb.com/images/M/209_.jpg");
   celebList.add(celeb2);
}
} //mainactivity

RecyclerTouchListener：

public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {
private GestureDetector gestureDetector;
private ClickListener clickListener;

public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener) {
    this.clickListener = clickListener;
    gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {

        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if (child != null && clickListener != null) {
                clickListener.onLongClick(child, recyclerView.getChildAdapterPosition(child));
            }
        }
    });
}

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
    View child = rv.findChildViewUnder(e.getX(), e.getY());
    if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
        clickListener.onClick(child, rv.getChildAdapterPosition(child));
    }
    return false;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}

}

点击监听器：

public interface ClickListener {
  void onClick(View view, int position);

  void onLongClick(View view, int position);
}
