我成功创建了SquareRelativeLayout。然后我将此CustomLayout用作GridLayout的一个网格项。我现在有5个项目(但它可以是变量)。对于第一行,一切都很好。我的项目大小为400 * 400但是对于第二行我有400 * 429的大小。我认为我的问题来自上面,实际上我使用的是LinearLayout,而我的GridLayout的布局高度为:权重0.50。这是我目前的布局:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mainContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="MainActivity">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#66000000">
<TextView
android:id="@+id/textView4"
android:layout_width="match_parent"
android:layout_height="0dp" ... />
<android.support.v7.widget.GridLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:grid="http://schemas.android.com/apk/res-auto"
android:id="@+id/droparea"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.50"
grid:columnCount="3"
grid:orientation="horizontal">
<SquareRelativeLayout
android:id="@+id/relativelayout"
android:layout_width="0dp"
android:layout_height="wrap_content"
grid:layout_columnWeight="1"
grid:layout_gravity="fill"
android:background="@drawable/round_layout"
android:gravity="center_vertical|center_horizontal">
...
</SquareRelativeLayout>
<SquareRelativeLayout
android:id="@+id/relativelayout2"
android:layout_width="0dp"
android:layout_height="wrap_content"
grid:layout_columnWeight="1"
grid:layout_gravity="fill"
android:background="@drawable/round_layout"
android:gravity="center_vertical|center_horizontal">
...
</SquareRelativeLayout>
<SquareRelativeLayout
android:id="@+id/relativelayout3"
android:layout_width="0dp"
android:layout_height="wrap_content"
grid:layout_columnWeight="1"
grid:layout_gravity="fill"
android:background="@drawable/round_layout"
android:gravity="center_vertical|center_horizontal">

</SquareRelativeLayout>
<SquareRelativeLayout
android:id="@+id/relativelayout4"
android:layout_width="0dp"
android:layout_height="wrap_content"
grid:layout_columnWeight="1"
grid:layout_gravity="fill"
android:background="@drawable/round_layout"
android:gravity="center_vertical|center_horizontal">
....
</SquareRelativeLayout>
<SquareRelativeLayout
android:id="@+id/relativelayout5"
android:layout_width="0dp"
android:layout_height="wrap_content"
grid:layout_columnWeight="1"
grid:layout_gravity="fill"
android:background="@drawable/round_layout"
android:gravity="center_vertical|center_horizontal">
...
</SquareRelativeLayout>
</android.support.v7.widget.GridLayout>
<include layout="@layout/draggable_linearlayout"/>
</LinearLayout>
</RelativeLayout>
这是我的SquareRelativeLayout的代码:
import android.content.Context;
import android.util.AttributeSet;
import android.widget.RelativeLayout;
public class SquareRelativeLayout extends RelativeLayout {
public SquareRelativeLayout(Context context) {
super(context);
}
public SquareRelativeLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public SquareRelativeLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, widthMeasureSpec);
}
}
所以我希望能够为GridLayout设置一个可变高度,但是要保持平方项。是否可以让GridLayout填充29dp?我错过了一个属性吗?如果你能帮助我,请不要犹豫:)
答案 0 :(得分:0)
这很简单,但昨天我没有考虑过。你只需要为GridLayout使用ParentLayout,然后设置GridLayout的layout_height属性wrap_content,就是这样:)
