我正在做一个类似whatsup的应用程序。我的问题是关于界面的。我可以得到一条消息 desc 并解析它。之后我可以以编程方式添加布局,但它一直在写相同的坐标。我尝试tv.layout(l, t, r, b)
了 tv.setTop 但不起作用。
我的问题在哪里?
bubbleLayout=(RelativeLayout)findViewById(R.id.layoutbubble);
for(int i=0;i<msgid.length;i++){
RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT);
// Creating a new TextView
TextView tv = new TextView(this);
tv.setText(msgdesc[i]);
tv.setTop(20);
// Defining the layout parameters of the TextView
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
// Setting the parameters on the TextView
tv.setLayoutParams(lp);
// Adding the TextView to the RelativeLayout as a child
bubbleLayout.addView(tv);
我的 XML 文件:
