Android Toast效果设置
Toast是Android中用来显示显示信息的一种机制,和Dialog不一样的是,Toast是没有焦点的,而且Toast显示的时间有限,过一定的时间就会自动消失。总结Toast显示的几种方法:
1.默认效果:
居中显示在屏幕底部!
代码:
Toast.makeText(context, "默认样式",Toast.LENGTH_SHORT).show();
2.
自定义显示位置效果:
可以摆放在屏幕不同的位置!
代码:
//屏幕居中显示
Toast toast = Toast.makeText(getApplicationxContet(),
"自定义位置Toast", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);//通过设置Gravity来显示位置
toast.show();
//显示在离titlebar 60dp的位置并且,宽度适应屏幕大小
Toast toast = Toast.makeText(context,
"自定义位置Toast", Toast., );
toast.show();
3.完全自定义效果:
布局完全自定义自己的布局
代码:
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom,//为自定义布局的名字
(ViewGroup) findViewById(R.id.llToast));
ImageView image = (ImageView) layout
.findViewById(R.id.tvImageToast);
image.setImageResource(R.drawable.icon);
TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
title.setText("Attention");
TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
text.setText("完全自定义Toast");
toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();
4.带图片效果:
在屏幕上显示一块图片
代码:
Toast toast = Toast.makeText(context,
"带图片的Toast", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
LinearLayout toastView = (LinearLayout) toast.getView();
ImageView imageCodeProject = new ImageView(getApplicationContext());
imageCodeProject.setImageResource(R.drawable.icon);
toastView.addView(imageCodeProject, 0);
toast.show();
5.其他线程:
开线程显示Toast
代码:
new Thread(new Runnable() {
public void run() {
Toast.makeText(context, "默认样式",Toast.LENGTH_SHORT).show();
}
}).start();
