Android基础控件——AlertDialog、ProgressDialog实现单选对话框、多选对话框、进度条对话框、输入框对话框

AlertDialog、ProgressDialog实现单选对话框、多选对话框、进度条对话框、输入框对话框事先说明：对话框应选用android.support.v7这个包底下的组件，能在低版本中展示高版本的对话框，简单的说漂亮很多属性介绍：

setCancelable : 设置对话框能否被手动关闭

步骤一：确认对话框

private void showConfirmDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("提醒");
builder.setMessage("是否确认更新？");
builder.setPositiveButton("更新", 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) {

}
});
builder.show();
}

步骤二：单选对话框

private void showSingleDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("请选择");
String[] items = new String[]{"条目一", "条目二", "条目三"};
//参数一：选择框的条目的值
//参数二：默认选择条目
builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//items[which]被选中
}
});
builder.show();
}

步骤三：多选对话框

    private void showMultiDialog() {AlertDialog.Builder builder = new AlertDialog.Builder(this);builder.setTitle("请选择");String[] items = new String[]{"条目一", "条目二", "条目三"};//参数一：选择框的条目的值//参数二：默认选择条目builder.setMultiChoiceItems(items, new boolean[]{true, false, false}, new DialogInterface.OnMultiChoiceClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which, boolean isChecked) {//items[which]被选中}});builder.show();}

步骤四：圆形进度条对话框

    private void showRoundProgressDialog() {ProgressDialog pd = new ProgressDialog(this);pd.setTitle("更新中");pd.setMessage("系统正在升级");pd.show();}

步骤五：水平进度条对话框

    private void showHorizontalProgressDialog() {ProgressDialog pd = new ProgressDialog(this);pd.setTitle("更新中");pd.setMessage("系统正在升级");pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);pd.show();}

步骤六：输入框对话框

布局文件view_username_dilog.xml文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical"><EditTextandroid:id="@+id/et_name"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_margin="16dp" /></LinearLayout>

代码中实现：

    public static void showUserNameDialog() {LayoutInflater factory = LayoutInflater.from(this);View view = factory.inflate(R.layout.view_username_dialog, null);AlertDialog.Builder builder = new AlertDialog.Builder(this);builder.setTitle("昵称");builder.setView(view);builder.setPositiveButton("是", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int i) {}});builder.setNegativeButton("否", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int i) {}});builder.show();}
