Dialog的2种常用样式

1.

直接对Dialog使用

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        // 标题
        builder.setTitle("我是标题");
        // 内容
        builder.setMessage("我是内容");
        // 禁止取消(按返回键或对话框周围屏幕)
        builder.setCancelable(false);
        // 确认按钮
        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // 处理按钮逻辑
                    }
        });
        // 取消按钮
        builder.setNegativeButton("取消",new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // 处理按钮逻辑
                    }
        });
        builder.show();// 内部会自动调用create方法

2.

用自己自定义的布局，加载dialog

布局如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/dialog_title_background"
        android:drawablePadding="3dp"
        android:gravity="center_vertical"
        android:padding="3dp"
        android:text="请输入内容"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="3dp">

        <EditText
            android:id="@+id/dialog_sjfd_input_pwd_edt_pwd"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:hint="请输入内容"
            android:inputType="textPassword"/>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:orientation="horizontal">

            <Button
                android:id="@+id/dialog_sjfd_input_pwd_btn_ok"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="确定"
                />

            <Button
                android:id="@+id/dialog_sjfd_input_pwd_btn_cancel"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_marginLeft="5dp"
                android:layout_weight="1"
                android:text="取消"/>
        </LinearLayout>
    </LinearLayout>

</LinearLayout>

代码

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        //填充自定义view
        View view = View.inflate(this, R.layout.dialog_sjfd_input_pwd, null);
        //对话框设置自定义view
        builder.setView(view);
        final AlertDialog dialog = builder.create();
        //初始化控件
        final EditText edtPwd = (EditText) view.findViewById(R.id.dialog_sjfd_input_pwd_edt_pwd);
        Button btnOk = (Button) view.findViewById(R.id.dialog_sjfd_input_pwd_btn_ok);
        Button btnCancel = (Button) view.findViewById(R.id.dialog_sjfd_input_pwd_btn_cancel);
        //设置监听
        btnOk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //隐藏对话框
                dialog.dismiss();
            }
        });
        btnCancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //隐藏对话框
                dialog.dismiss();
            }
        });
        dialog.show();
