</LinearLayout>

自定义dialog背景

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <size android:height="40dp" android:width="40dp"/>
    <solid android:color="#EFEFEF"/>
    <corners android:radius="12dp"/>

</shape>

dialog样式

 <style name="CustomDialog" parent="@android:style/Theme.Dialog">
        <!--这个说明提示框是否有边框-->
        <item name="android:windowFrame">@null</item>
        <!--这个说明提示框是否是浮动的-->
        <item name="android:windowIsFloating">true</item>
        <!--这个说明提示框是滞是透明的-->
        <item name="android:windowIsTranslucent">false</item>
        <!--这个说明提示框是否有标题-->
        <item name="android:windowNoTitle">true</item>
        <!--这个说明提示框的背景颜色是什么-->
        <item name="android:windowBackground">@drawable/bg_dialog_confirm</item>
        <!--这个说明是否充许对话框的背景变暗。为true则充许变暗-->
        <item name="android:backgroundDimEnabled">true</item>
    </style>

定义接口

public interface CustomDialogClicklistener {
    void doConfirm();

    void doCancel();
}

主要代码

public class CustomDialog extends Dialog implements View.OnClickListener {
    Context mContext;
    private TextView btnSure;
    private TextView btnCancle;
    private TextView title;
    private TextView message;
    private CustomDialogClicklistener customDialogClicklistener;

    public CustomDialog(@NonNull Context context, CustomDialogClicklistener clicklistener) {
        super(context, R.style.CustomDialog);
        this.mContext = context;
        this.customDialogClicklistener = clicklistener;
        initView();
    }

    public void initView() {
        View view = LayoutInflater.from(mContext).inflate(R.layout.my_dialog, null);
        title = (TextView) view.findViewById(R.id.title);
        message = (TextView) view.findViewById(R.id.message);
        btnSure = (TextView) view.findViewById(R.id.dialog_confirm_sure);
        btnCancle = (TextView) view.findViewById(R.id.dialog_confirm_cancle);
        btnSure.setOnClickListener(this);
        btnCancle.setOnClickListener(this);
        super.setContentView(view);
    }

    //对外提供设置标题的方法
    public CustomDialog setTile(String s) {
        title.setText(s);
        return this;
    }

    //对外提供设置提示信息的方法
    public CustomDialog setMessage(String s) {
        message.setText(s);
        return this;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.dialog_confirm_sure:
                CustomDialog.this.cancel();
                customDialogClicklistener.doConfirm();
                break;
            case R.id.dialog_confirm_cancle:
                CustomDialog.this.cancel();
                customDialogClicklistener.doCancel();
                break;
        }
    }
}

最后就是引用了

 public void showDialog1() {
        CustomDialog customDialog = new CustomDialog(this, new CustomDialogClicklistener() {
            @Override
            public void doConfirm() {
                Toast.makeText(MainActivity.this, "你点击了确定", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void doCancel() {
                Toast.makeText(MainActivity.this, "你点击了取消", Toast.LENGTH_SHORT).show();
            }
        });
        customDialog.setTile("温馨提示");
        customDialog.setMessage("是否退出");
        customDialog.show();
    }

2.带输入框的对话框

自定义输入框背景

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <!--设置圆角-->
    <corners android:radius="0dp" />
    <!--设置边框-->
    <stroke

        android:color="#d7d7db" />
    <!--设置填充色-->
    <solid android:color="#f8f8f8" />
</shape>

主要代码

public class CustomEditTextDialog extends Dialog {
    Context mContext;
    private TextView btnSure;
    private TextView btnCancle;
    private TextView title;
    private EditText editText;

    public CustomEditTextDialog(@NonNull Context context) {
        super(context, R.style.CustomDialog);
        this.mContext = context;
        initView();
    }

    //初始化
    public void initView() {
        View view = LayoutInflater.from(mContext).inflate(R.layout.edit_dialog, null);
        title = (TextView) view.findViewById(R.id.title);
        editText = (EditText) view.findViewById(R.id.edittext);
        btnSure = (TextView) view.findViewById(R.id.dialog_confirm_sure);
        btnCancle = (TextView) view.findViewById(R.id.dialog_confirm_cancle);
        super.setContentView(view);
    }


    public CustomEditTextDialog setTile(String s) {
        title.setText(s);
        return this;
    }

    //获取当前输入框对象
    public View getEditText() {
        return editText;
    }

    //确定键监听器
    public void setOnSureListener(View.OnClickListener listener) {
        btnSure.setOnClickListener(listener);
    }

    //取消键监听器
    public void setOnCanlceListener(View.OnClickListener listener) {
        btnCancle.setOnClickListener(listener);
    }
}

对话框的引用

 public void showDialog2() {
        final CustomEditTextDialog customDialog = new CustomEditTextDialog(this);
        final EditText editText = (EditText) customDialog.getEditText();//方法在CustomDialog中实现
        customDialog.setOnSureListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "你点击了确定,输入的值为:"+editText.getText().toString(), Toast.LENGTH_SHORT).show();
                customDialog.dismiss();
            }
        });
        customDialog.setOnCanlceListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "你点击了取消", Toast.LENGTH_SHORT).show();
                customDialog.dismiss();
            }
        });
        customDialog.setTile("请输入名字");
        customDialog.show();
    }
