如何在Android中动态地将TextView添加到LinearLayout？

Question

我尝试将添加TextView到LinearLayout动态，如下面的代码，但是当我运行该应用程序也不会出现？setContentView(R.layout.advanced);m_vwJokeLayout=(LinearLayout) this.findViewById(R.id.m_vwJokeLayout);m_vwJokeEditText=(EditText) this.findViewById(R.id.m_vwJokeEditText);m_vwJokeButton=(Button) this.findViewById(R.id.m_vwJokeButton);TextView tv=new TextView(this);tv.setText("test");this.m_vwJokeLayout.addView(tv);有什么问题？

Answer 1

LayoutParams lparams = new LayoutParams(

   LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

TextView tv=new TextView(this);

tv.setLayoutParams(lparams);

tv.setText("test");

this.m_vwJokeLayout.addView(tv);

您可以根据需要更改lparams
