在Android中以编程方式设置textview

Question

我想以编程方式设置textview，以下代码似乎无法正常工作

TextView textView = new TextView(this);  
textView.setText("game");  
setContentView(textView);

Answer 1

更改

TextView textView = new TextView(this);

到

TextView textView = new TextView(Youractivity.this);

Answer 2

在setContentView(....);

之前的任意位置删除TextView textView = new TextView(this);

Answer 3

试试这个

TextView textView = new TextView(this);  
textView.setText("game");  

textView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
setContentView(textView);

Answer 4

创建LayoutParams，如下所示

LayoutParams  param=new LayoutParams(w, h);
           textView.setLayoutParams(param);
