java - Android Grid布局展示

Question

我在 Android 应用程序中使用了 GridLayout，但我遇到了显示问题，

我使用 setColumnCount 来设置 3 列，因为我必须每行添加 3 个元素，所以它应该对齐。

layout1 = new GridLayout(this);
layout1.setColumnCount(3);

 //In a loop later in the code :
layout1.addView(textView1);
layout1.addView(cb);
layout1.addView(textView2);

3个项目没有对齐，但都在第一列，我不太明白这个问题。

为您的 subview 使用 LayoutParams

GridLayout gridLayout = new GridLayout(this);
gridLayout.setColumnCount(colCount);
gridLayout.setRowCount(rowCount);

GridLayout.LayoutParams third = new GridLayout.LayoutParams(0, 0);
textView1.setLayoutParams(third);
gridLayout.addView(textView1, third);

GridLayout.LayoutParams fourth = new GridLayout.LayoutParams(0, 1);
cb.setLayoutParams(fourth);
gridLayout.addView(cb, fourth);

GridLayout.LayoutParams fifth = new GridLayout.LayoutParams(0, 2);
textView2.setLayoutParams(fifth );
gridLayout.addView(textView2, fifth);
