android获取Button文本 从一个按钮开关中获取文本
在程序里可以从一个按钮中获取文本
String buttonText = button.getText();
也可以从按钮开关中获取id
int buttinID = view.getId();
但是如何从按钮开关中获取文本呢？这俩个怎么结合呢？
在onClick()中传递的视图就是你要找的button,需要强制转换一下。
public void onClick(View view) {
// 从按钮开关中获取文本
Button b = (Button)v;
String buttonText = b.getText().toString();
}
