// 新建一个toast对象
private Toast toast;
public void showMsg(String arg) {
if (toast == null) {
toast = Toast.makeText(this, arg, Toast.LENGTH_SHORT);
} else {
toast.cancel();
toast.setText(arg);
}
toast.show();
}
res/drawable目录下面建立一个设置圆角边框参数的xml文件，如下：
corner_round.xml:
复制代码
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#FFCC33" />
<corners android:radius="10dp" />
</shape>
复制代码
调用：android:background="@drawable/corner_round"
