如何在Android开发中熟练使用五种Toast的特效

Answer 1

1 

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。默认效果,代码为：

Toast.makeText(getApplicationContext(), "默认Toast样式", Toast.LENGTH_SHORT).show();

2

自定义显示位置效果,代码为：

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,代码为：

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,代码为：

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();

其他线程,代码为：

new Thread(new Runnable() {    public void run() {     showToast();    }   }).start();
