我正在使用LayoutInflater使用GridAdapter填充网格视图,但是当我尝试将textView放到布局中的另一个textView下方时,我会膨胀,它最终位于我的textView上方而不是下方。当我改为将其更改为layout_above时,它甚至没有出现在屏幕上。 我膨胀的布局:
<?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="match_parent"
android:id="@+id/menuBookModel">
<ImageView
android:id="@+id/bookImage"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_margin="5dp"/>
<TextView
android:id="@+id/bookName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test Text"
android:textSize="20sp"
android:textColor="@color/colorPrimaryDark"
android:layout_centerInParent="true"/>
<TextView
android:id="@+id/personalTag"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/bookName"
android:text="(Personal)"
android:layout_centerHorizontal="true"
android:textColor="@color/colorPrimaryDark"
android:textSize="15sp" />
</RelativeLayout>
我正在膨胀的Java代码:
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if(view == null){
view = inflater.inflate(R.layout.menu_book_model, null);
}
TextView bookName = view.findViewById(R.id.bookName);
TextView personalTag = view.findViewById(R.id.personalTag);
ImageView bookImage = view.findViewById(R.id.bookImage);
bookImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String s = String.valueOf(view.getTag());
aListener.chooseBook(s);
}
});
int id = context.getResources().getIdentifier(books[i], "string", context.getPackageName());
//if id == 0 the book is custom, and therefore it has the custom name
if(id == 0){
bookName.setText(books[i]);
} else {
bookName.setText(context.getString(id));
personalTag.setVisibility(View.GONE);
}
bookImage.setBackgroundColor(Color.rgb(random.nextInt(255),random.nextInt(255),random.nextInt(255)));
bookImage.setTag(books[i]);
return view;
}
预览中的外观: Preview
但这是实际的样子: In practice
答案 0 :(得分:0)
当personalTag
为0时,您还需要处理id
的可见性,因为在回收视图时它可能不可见:
if(id == 0){
bookName.setText(books[i]);
personalTag.setVisibility(View.VISIBLE);
} else {
bookName.setText(context.getString(id));
personalTag.setVisibility(View.GONE);
}
还要避免将RelativeLayout
的根match_parent
设置为高度,它们通常会在AdapterViews
中 break ,尝试使用wrap_content
或任何硬值,或调整您的布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="100dp"
android:id="@+id/menuBookModel">
<ImageView
android:id="@+id/bookImage"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_margin="5dp"/>
<TextView
android:id="@+id/bookName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test Text"
android:layout_centerInParent="true"
android:textSize="20sp"
android:textColor="@color/colorPrimaryDark"/>
<TextView
android:id="@+id/personalTag"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/bookName"
android:layout_centerHorizontal="true"
android:text="(Personal)"
android:textColor="@color/colorPrimaryDark"
android:textSize="15sp" />
</RelativeLayout>
