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

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() {            @Override            public 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">    <EditText        android: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();    }
