下面是自己总结的Android常用的几种Dialog：
1.AlertDialog android中功能最丰富，用途最广的对话框。
// 1 创建一个Builder
AlertDialog.Builder builder = new AlertDialog.Builder(this);
// 2 给Builder设置属性
builder.setTitle("Java培训");// 设置Dialog的标题
builder.setMessage("访问OSC的网页");// 设置Dialog的信息
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {// 设置确定按钮
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getApplicationContext(), "访问OSC的网页", 0).show();
}
});
builder.setNeutralButton("隐藏", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
//从上我们可以看出Dialog的按钮一般分为了三种，确定builder.setPositiveButton(),隐藏builder.setNeutralButton,取消builder.setNegativeButton
// 3 创建Dialog
AlertDialog dialog = builder.create();
// 4 显示Dialog
dialog.show();
2.ListDialog,设置选项的时候用如下代码：
final String[] items = { "java", "donet", "php" };
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getApplicationContext(), items[which], 0).show();
}
});
3.singleItemDialog，这样子能够让选项以单选框的样式呈现出来：
builder.setSingleChoiceItems(items, 2, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getApplicationContext(), items[which], 0).show();
}
});
4.多选框的Dialog
final String[] items = { "java", "donet", "php" };
final boolean[] checkedItems = new boolean[] { true, false, false };
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("选择语言");
builder.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
Toast.makeText(getApplicationContext(), items[which] + isChecked, 0).show();
}
});
5.进度条的dialog
ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);// 设置为水平进度条
progressDialog.setTitle("正在下载。。。");
progressDialog.setMax(100);// 设置进度条的最大值
progressDialog.setCancelable(false);// 设置回退键失效
progressDialog.setButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
progressDialog.show();
progressDialog.setProgress(50);// 设置进度条的当前刻度
注意的是Dialog是activity的一个控件，弹出Dialog的时候，activity是不会失去焦点的，也就是说activity不会调用onPause()方法
