在第二项中它似乎是重叠元素。这可能是由于文本较长但我无法修复它。   fragment_meds.xml

            super(view);
            mView = view;
            mIdView = (TextView) view.findViewById(R.id.id);
            mContentView = (TextView) view.findViewById(R.id.content);
            resupply_button = (TextView) view.findViewById(R.id.resupply_button);

        }

        @Override
        public String toString() {
            return super.toString() + " '" + mContentView.getText() + "'";
        }


    }


}
  

上面我添加了相关的代码，在这里我需要提一下我禁用了Recycle-view的项目可重用性功能。如果有人可以帮我解决这个问题，我将不胜感激。

尝试这样

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="175dp"

    android:layout_width="100dp"
    android:layout_height="100dp"
    android:padding="10dp"
    android:src="@drawable/default_meds_small"/>


<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_toRightOf="@+id/iv"
    android:paddingTop="10dp"
    android:orientation="vertical">

    <TextView

不使用 LinearLayout 仅用于一个小部件，您可以直接使用Imageview 

    <ImageView
    android:background="@drawable/default_meds_small"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:adjustViewBound="true"
    android:padding="10dp"
    android:layout_weight="0.35" />
