    由于开发中经常使用弹框，然而系统自带的弹框太局限，也不太美观，经常不能满足开发需求，所以就只能自定义布局。其实自定义布局很简单，没不要写出来，但是如果不写一遍的，后面遇到的话就感觉又会忘记，所以在次记一小笔，仅记一个最简单的例子，可以举一反三。

直接上代码:

dialog_setting_wifi_pwd.xml 

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/Transparent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_margin="30dp"
        android:background="@drawable/dialog_white_bg"
        android:orientation="vertical"
        android:padding="5dp">

        <AutoCompleteTextView
            android:id="@+id/dialog_setting_first_input_pwd"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@null"
            android:drawableBottom="@drawable/line_bottom"
            android:gravity="center_vertical"
            android:hint="请输入新密码"
            android:padding="5dp"
            android:textColor="@color/black"
            android:textColorHint="@color/graywhite"
            android:textSize="20sp" />

        <AutoCompleteTextView
            android:id="@+id/dialog_setting_second_input_pwd"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:background="@null"
            android:drawableBottom="@drawable/line_bottom"
            android:gravity="center_vertical"
            android:hint="请输入确认密码"
            android:padding="5dp"
            android:textColor="@color/black"
            android:textColorHint="@color/graywhite"
            android:textSize="20sp" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center">

            <Button
                android:id="@+id/dialog_setting_sure"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="10dp"
                android:background="@drawable/btn_sure_nor"
                android:text="@string/sure"
                android:textColor="@color/white"
                android:textSize="20sp" />

            <Button
                android:id="@+id/dialog_setting_cancle"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="10dp"
                android:background="@drawable/btn_cancel_nor"
                android:text="@string/cancle"
                android:textColor="@color/black"
                android:textSize="20sp" />

        </LinearLayout>

    </LinearLayout>

</RelativeLayout>

其中背景： dialog_white_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- android:radius 弧形的半径 -->
    <corners android:radius="15dp" />

    <!-- 填充的颜色 -->
    <solid android:color="@android:color/white" />

</shape>

 Activity代码中使用：

textView_camera_info_pwd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                final AlertDialog.Builder editDialog = new AlertDialog.Builder(MenuActivity.this);
                LayoutInflater inflater = LayoutInflater.from(MenuActivity.this);
                View v = inflater.inflate(R.layout.dialog_setting_wifi_pwd, null);
                final AutoCompleteTextView firstPwd = v.findViewById(R.id.dialog_setting_first_input_pwd);
                final AutoCompleteTextView secondPwd = v.findViewById(R.id.dialog_setting_second_input_pwd);
                Button btnSure = v.findViewById(R.id.dialog_setting_sure);
                Button btnCancle = v.findViewById(R.id.dialog_setting_cancle);
                editDialog.setView(v);
                editDialog.setCancelable(true);
                final AlertDialog alertDialog = editDialog.create();
                alertDialog.show();

                btnSure.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        setLoading(true);
                        NVTKitModel.removeWifiEventListener();
                        new Thread(new Runnable() {
                            @Override
                            public void run() {
                                if (!TextUtils.isEmpty(firstPwd.getText().toString())) {
                                    if (firstPwd.getText().toString().equals(secondPwd.getText().toString())) {
                                        String result = NVTKitModel.netSetPassword("" + secondPwd.getText());
                                        if (result == null) {
                                            Log.e(TAG, "set_passphrase fail");
                                        }
                                        try {
                                            Thread.sleep(6000);
                                        } catch (InterruptedException e) {
                                            // TODO Auto-generated catch block
                                            e.printStackTrace();
                                        }
                                        checkDevDialog();
                                    } else {
                                        runOnUiThread(new Runnable() {
                                            @Override
                                            public void run() {
                                                Toast.makeText(MenuActivity.this, "两次输入的密码不一致", Toast.LENGTH_SHORT).show();
                                            }
                                        });
                                    }

                                } else {
                                    runOnUiThread(new Runnable() {
                                        @Override
