每日总结
直接调用Toast类的makeText()方法创建
这是我们用的最多的一种形式了!比如点击一个按钮,然后弹出Toast,用法: Toast.makeText(MainActivity.this, "提示的内容", Toast.LENGTH_LONG).show();
第一个是上下文对象!对二个是显示的内容!第三个是显示的时间,只有LONG和SHORT两种 会生效
示例代码:
void midToast(String str, int showTime)
{
Toast toast = Toast.makeText(global_context, str, showTime);
toast.setGravity(Gravity.CENTER_VERTICAL|Gravity.CENTER_HORIZONTAL , 0, 0); //设置显示位置
TextView v = (TextView) toast.getView().findViewById(android.R.id.message);
v.setTextColor(Color.YELLOW); //设置字体颜色
toast.show();
}
实现完全自定义:
private void midToast(String str, int showTime)
{
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.view_toast_custom,
(ViewGroup) findViewById(R.id.lly_toast));
ImageView img_logo = (ImageView) view.findViewById(R.id.img_logo);
TextView tv_msg = (TextView) view.findViewById(R.id.tv_msg);
tv_msg.setText(str);
Toast toast = new Toast(mContext);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(view);
toast.show();
}
