Android：如何避免生成的文本视图在不同位置重叠？
我正在以编程的方式在主布局上生成不同的UI文本视图，并将其放置在不同的位置w.r.t不同的边距。当涉及到实现和测试时，生成的所有文本视图都是重叠的。您能告诉我如何将编程生成的文本视图放在不同的位置吗 以下是我的方法：Android：如何避免生成的文本视图在不同位置重叠？,android,textview,android-relativelayout,Android,Textview,Android Relativelayout,我正在以编程的方式在主布局上生成不同的UI文本视图，并将其放置在不同的位置w.r.t不同的边距。当涉及到实现和测试时，生成的所有文本视图都是重叠的。您能告诉我如何将编程生成的文本视图放在不同的位置吗 以下是我的方法： setLabel(lblPairing , "PAIRING" , (int)(0.22*screenWidth), (int)(0.075*screenHeight) , ColorTool.changeTextColor("#e3e3e5"),
