概念：
一个对话框就是一个小窗口，并不会填满整个屏幕，通常是以模态显示，要求用户必须采取行动才能进行剩下操作。
类型：
AlertDialog：警告对话框，可以在下面定义按钮选项或者其他自定义。
ProgressDialog：进度条对话框
TimePickerDialog：时间对话框。
我们首先创建很多按钮。
然后使用Builder去创建对话框。导包选择Alert
直接上代码
//普通Dialog
public void alertDialog_bt1(View view)
{
AlertDialog.Builder builder=new AlertDialog.Builder(this);
// builder.setIcon(R.drawable.ic_category_0);
builder.setTitle("alert对话框");
builder.setMessage("这是两按钮的普通对话框");
builder.setPositiveButton("按钮1", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(Day9_Activity.this, "按钮1被点击了", Toast.LENGTH_SHORT).show();
}
});
builder.setNeutralButton("按钮2", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(Day9_Activity.this, "按钮2被点击了", Toast.LENGTH_SHORT).show();
}
});
builder.show();
} //列表Dialog
public void alertDialog_bt2(View view)
{
final String[] items = { "富强","民主","科学","自由" };
AlertDialog.Builder builder=new AlertDialog.Builder(this);
builder.setTitle("我是一个列表对话框");
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(Day9_Activity.this, "按钮"+ items[which]+"被点击了", Toast.LENGTH_SHORT).show();
}
});
builder.setPositiveButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(Day9_Activity.this, "取消了", Toast.LENGTH_SHORT).show();

builder.show();
}//单选对话框
