AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("多项选择");
builder.setMultiChoiceItems(Items,
new boolean[]{false, false, false, false, false, false, false},
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int whichButton, boolean isChecked) {
if(isChecked) {
MultiChoiceID.add(whichButton);
showDialog("你选择的id为" + whichButton + " , " + Items[whichButton]);
}else {
MultiChoiceID.remove(whichButton);
}
}
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String str = "";
int size = MultiChoiceID.size();
for (int i = 0 ;i < size; i++) {
str += Items[MultiChoiceID.get(i)] + ", ";
}
showDialog("你选择的是" + str);
}
});

点击进度条框按钮后 开启一个线程计算读取的进度 假设读取结束为 100.
Progress在小于100的时候一直在线程中做循环++ 只到读取结束后，停止线程。

* @author Andy
*/
public void CreateDialogs(){
final ProgressDialog proDialog = android.app.ProgressDialog.show(MainActivity.this, "测试", "等待2秒！");
Thread thread = new Thread() {
public void run() {
try {
sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
proDialog.dismiss();//必须在线程结束时调用对话框对象的dismiss()方法，否则程序将进入死循环当中
}
};
thread.start();
}
