android - LinearLayout 只允许添加一个 View

Question

  layout = new LinearLayout(this);
            addContentView(layout, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));


            Button btn = new Button(this);
            btn.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
           btn.setText("button");

            layout.addView(btn);

            Button btn1 = new Button(this);
            btn1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
           btn1.setText("button");

            layout.addView(btn1);

我知道我一定遗漏了一些东西，因为每当我向这个布局添加 View 时，我只会显示其中一个。

享受哥们

layout = new LinearLayout(this); 
layout.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
layout.setOrientation(LinearLayout.VERTICAL);
setContentView(layout);
layout.setOrientation(LinearLayout.VERTICAL);

重组这个 addContentView(layout, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

你没有设置方向，默认是水平的，你给了宽度 LayoutParams.FILL_PARENT
