Toast.makeText用法

Toast用于向用户显示一些帮助/提示。下面我做了5中效果，来说明Toast的强大，定义一个属于你自己的Toast。

1.默认效果




代码
Toast.makeText(getApplicationContext(), "默认Toast样式",

Toast.LENGTH_SHORT).show();
2.自定义显示位置效果



代码
toast = Toast.makeText(getApplicationContext(),

"自定义位置Toast", Toast.LENGTH_LONG);

toast.setGravity(Gravity.CENTER, 0, 0);

toast.show();
3.带图片效果



代码
toast = Toast.makeText(getApplicationContext(),

"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();
4.完全自定义效果



代码
LayoutInflater inflater = getLayoutInflater();

View layout = inflater.inflate(R.layout.custom,

(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();
5.其他线程






代码
new Thread(new Runnable() {

public void run() {

showToast();

}

}).start();
