我正在开发一个项目,我需要实现一个网格来显示“Widgets”(自定义视图),由最终用户动态重新排序。或多或少与Android Launchers及其小部件相同,可由用户通过网格移动的小部件(长按,与大多数启动器一样)。这是我正在寻找的预览: Every color represents one different kind of "Widget"
我尝试过使用GridLayout和TableLayout,但是我无法“合并”单元格来调整Widget的布局。
网格本身是一个8 x 12的单元格网格,其中Widgets每个可以使用1个以上的单元格,例如,我已经配置了一个2 x 3(h | w)的“Widget按钮”。
是否有适合我需要的布局,或者我必须创建自己的布局?
谢谢你,阿贝尔!

您的应用可以使用带有回收站视图的staggeredGridLayout吗? http://developer.android.com/reference/android/support/v7/widget/StaggeredGridLayoutManager.html

我使用以下代码以编程方式创建视图并设置其PercentRelativeLayout.LayoutParams
:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_percent_relative);
ViewGroup root = (ViewGroup)findViewById(R.id.perecent_layout_view);
View blueWidget = new View(this);
blueWidget.setBackground(blue);
root.addView(blueWidget);
setUpLayout(blueWidget, 2.0f/8.0f, 6.0f/8.0f, 6.0f/8.0f, 0.0f, 2.0f/8.0f, 0.0f);
View redWidget = new View(this);
redWidget.setBackground(red);
root.addView(redWidget);
setUpLayout(redWidget, 5.0f/8.0f, 2.0f/8.0f, 3.0f/8.0f, 0.0f, 0.0f, 6.0f/8.0f);
}
private void setUpLayout(View view, float widthPercent,
float heightPercent,
float leftMarginPercent,
float rightMarginPercent,
float topMarginPercent,
float bottomMarginPercent) {
PercentRelativeLayout.LayoutParams layoutParams = new PercentRelativeLayout.LayoutParams(view.getLayoutParams());
PercentLayoutHelper.PercentLayoutInfo percentLayoutInfo = layoutParams.getPercentLayoutInfo();
percentLayoutInfo.heightPercent = heightPercent;
percentLayoutInfo.widthPercent = widthPercent;
percentLayoutInfo.topMarginPercent= topMarginPercent;
percentLayoutInfo.bottomMarginPercent= bottomMarginPercent;
percentLayoutInfo.leftMarginPercent= leftMarginPercent;
percentLayoutInfo.rightMarginPercent= rightMarginPercent;
view.setLayoutParams(layoutParams);
}
