Android之Toast通知的几种自定义用法-白红宇

Toast在手机屏幕上向用户显示一条信息，一段时间后信息会自动消失。

1.默认用法

[html]

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

2.Fragment中的用法

[html]

Toast.makeText(getActivity(),"网络连接错误，请检察网络设置", Toast.LENGTH_LONG).show();

3.自定义显示位置效果

[html]

toast = Toast.makeText(getApplicationContext(), "自定义位置Toast", Toast.LENGTH_LONG);

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

toast.show();

4.带图片效果

[html]

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();

5.完全自定义效果

[html]

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();

6.其他线程
