Question

我想以编程方式向布局添加多个按钮。但是，按钮的数量每次都不同，我只是希望它们以包裹内容宽度彼此相邻放置。填充一行后，它应该转到下一行并继续这样。

实现这一目标的最简洁方法是什么？

感谢。

Answer 1

LinearLayout verticalLayout = new LinearLayout(context);
verticalLayout.setOrientation(LinearLayout.VERTICAL);

while(isActive) {
LinearLayout horziontalLayout = new LinearLayout(context);
horziontalLayout.setOrientation(LinearLayout.HORIZONTAL);
    add buttons here..
//Example Button button = new Button(context);
//horziontalLayout.addView(button);
verticalLayout.addView(horziontalLayout);

isActive = false // when youe done filling up buttons..
 }

Answer 2

最简单的方法应该是添加多个水平LinearLayout的垂直LinearLayout

//vertical one
LinearLayout vlinear = new LinearLayout(this);
vlinear.setOrientation(LinearLayout.VERTICAL);
LayoutParams vlinearParams = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
vlinear.setLayoutParams(vlinearParams);
parentgroup.addView(vlinear);

//horizontal lines
for (int i=0;i<numlines){
    LinearLayout hlinear = new LinearLayout(this);
      hlinear.setOrientation(LinearLayout.HORIZONTAL);
LayoutParams vlinearParams = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
hlinear.setLayoutParams(hlinearParams);
vlinear.addView(hlinear);
///add the loop for adding cells
for...
hlinear.addView(cell);
    }

在Android中没有网格的情况下将多个按钮放置到相对布局
