布局文件
布局是很简单的,一个显示数据表格,直接上布局:
布局/activity_add_photo.xml
& lt; & # 63; xml version=" 1.0 " encoding=" utf - 8 " & # 63;比;
& lt; LinearLayout xmlns: android=" http://schemas.android.com/apk/res/android "
android: layout_width=" match_parent "
android: layout_height=" match_parent "
面向android:=按怪薄北?
& lt;使用
android: layout_width=" match_parent "
android: layout_height=" 60 dp "
android:背景=" # 00 bb9c”比;
& lt; TextView
android: layout_width=" wrap_content "
android: layout_height=" wrap_content "
android: layout_centerInParent=" true "
android:文本="写动态”
android: textAppearance=" & # 63; android: attr/textAppearanceLarge”
android:输入textColor=癅android:颜色/白色/比;
& lt; TextView
android: id=癅 + id/发送”
android: layout_width=" wrap_content "
android: layout_height=" wrap_content "
android: layout_alignParentRight=" true "
android: layout_centerVertical=" true "
android: layout_marginRight=" 10 dp”
android:文本="发送”
android: textAppearance=" & # 63; android: attr/textAppearanceLarge”
android:输入textColor=癅android:颜色/白色/比;
& lt;/RelativeLayout>
LinearLayout & lt;
android: layout_width=" match_parent "
android: layout_height=" match_parent "
android: layout_margin=" 16 dp "
面向android:=按怪薄北?
EditText & lt;
android: layout_width=" match_parent "
android: layout_height=" 100 dp”
android:启用=" false "
android: focusable=" false "
android:重力=岸ゼ丁?
android:提示="分享您的那点新鲜事儿……”
android: maxLines=" 5 "/比;
LinearLayout & lt;
android: layout_width=" match_parent "
android: layout_height=" match_parent "
android:填充=" 5 dp "比;
& lt;显示数据表格
android: id=癅 + id/显示数据表格”
android: layout_width=" match_parent "
android: layout_height=" wrap_content "
android: numColumns=" 4 "/比;
& lt;/LinearLayout>
& lt;/LinearLayout>
& lt;/LinearLayout>
之前
/activity_add_photo_gv_items布局。xml使用了自定义的观点使得布局为正方形
& lt; & # 63; xml version=" 1.0 " encoding=" utf - 8 " & # 63;比;
& lt; com.shenhua.tabhostdemo.selectimg。SquareRelativeLayout xmlns: android=" http://schemas.android.com/apk/res/android "
android: layout_width=" wrap_content "
android: layout_height=皐rap_content”比;
& lt; ImageView
android: id=癅 + id/main_gridView_item_photo”
android: layout_width=" match_parent "
android: layout_height=" match_parent "
android: layout_centerInParent=" true "
android: contentDescription=" @null "
android:填充=" 5 dp "
android: scaleType=" fitXY "/比;
& lt;复选框
android: id=癅 + id/main_gridView_item_cb”
android: layout_width=" 20 dp”
android: layout_height=" 20 dp”
android: layout_alignParentEnd=" true "
android: layout_alignParentRight=" true "
android: layout_alignParentTop=" true "
android: layout_margin=" 2 dp "
android:背景=" @drawable/ic_delete”
android: backgroundTint=" # 00 bb9c”
android:按钮=" @null "/比;
