在运行时Android添加textview动态

Question

我想在Android上运行时添加Text-view，以在活动上显示我的数据库内容，每次都可以更改。 请帮忙

Answer 1

您可以像这样动态创建TextView，例如：

//create a TextView with Layout parameters according to your needs
LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
//if your parent Layout is relativeLayout, just change the word LinearLayout with RelativeLayout
TextView tv=new TextView(this);
tv.setLayoutParams(lparams);
tv.setText("test");
//get the parent layout for your new TextView and add the new TextView to it
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll_example);
linearLayout.addView(tv);

在tv.setText(...);行中，您可以设置从数据库中获取的文本。
