消息模式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",
<wbr><wbr><wbr><wbr>Toast.LENGTH_SHORT).show();</wbr></wbr></wbr></wbr>

2.自定义显示位置效果

代码

toast = Toast.makeText(getApplicationContext(),
<wbr><wbr><wbr><wbr>"自定义位置Toast", Toast.LENGTH_LONG);<br><wbr><wbr>toast.setGravity(Gravity.CENTER, 0, 0);<br><wbr><wbr> toast.show();</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

3.带图片效果

代码

toast = Toast.makeText(getApplicationContext(),
<wbr><wbr><wbr><wbr>"带图片的Toast", Toast.LENGTH_LONG);<br><wbr><wbr>toast.setGravity(Gravity.CENTER, 0, 0);<br><wbr><wbr> LinearLayout toastView =(LinearLayout) toast.getView();<br><wbr><wbr> ImageView imageCodeProject =new ImageView(getApplicationContext());<br><wbr><wbr>imageCodeProject.setImageResource(R.drawable.icon);<br><wbr><wbr>toastView.addView(imageCodeProject, 0);<br><wbr><wbr> toast.show();</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

4.完全自定义效果

代码

LayoutInflater inflater = getLayoutInflater();
<wbr><wbr> View layout =inflater.inflate(R.layout.custom,<br><wbr><wbr><wbr><wbr>(ViewGroup) findViewById(R.id.llToast));<br><wbr><wbr> ImageView image = (ImageView)layout<br><wbr><wbr><wbr><wbr>.findViewById(R.id.tvImageToast);<br><wbr><wbr>image.setImageResource(R.drawable.icon);<br><wbr><wbr> TextView title = (TextView)layout.findViewById(R.id.tvTitleToast);<br><wbr><wbr>title.setText("Attention");<br><wbr><wbr> TextView text = (TextView)layout.findViewById(R.id.tvTextToast);<br><wbr><wbr>text.setText("完全自定义Toast");<br><wbr><wbr> toast = newToast(getApplicationContext());<br><wbr><wbr> toast.setGravity(Gravity.RIGHT| Gravity.TOP, 12, 40);<br><wbr><wbr>toast.setDuration(Toast.LENGTH_LONG);<br><wbr><wbr> toast.setView(layout);<br><wbr><wbr> toast.show();</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

5.其他线程

<wbr>代码</wbr>

new Thread(new Runnable() {
<wbr><wbr><wbr> public voidrun() {<br><wbr><wbr><wbr><wbr>showToast();<br><wbr><wbr><wbr> }<br><wbr><wbr> }).start();</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
