LinearLayout只允许添加一个视图

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);

我知道我必须缺少一些东西，因为每当我将视图添加到此布局时，我只有其中一个显示出来。LinearLayout只允许添加一个视图

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);

Reome这addContentView(layout, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

您没有设置Oreientation，默认是水平的，你给宽度LayoutParams.FILL_PARENT

layout = new LinearLayout(this); 
layout .setOrientation(LinearLayout.VERTICAL); // orientation vertical try 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);

线性布局的方向必须是水平的。将其更改为垂直
