Android自定义类iPhone圆角dialog

其实android自定义的dialog都已经足够好了,但是有时候产品还是会设计出类似于iPhone的圆角dialog,今天抽空就将自己写的总结出来,以后用的时候直接来扒代码就好了。

相信很多人也写过类似的,但是有时候出现一个默认dialog的背景,然后就看着好丑。就先扯到这儿,上我自己自定义运行的截图:

其实代码没有多少先写自定义的布局文件:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="136dp"
    android:background="@drawable/white_shape_8"
    android:orientation="vertical">

    <LinearLayout
        android:id="@+id/callback_dialog_ll_top"
        android:layout_width="match_parent"
        android:layout_height="36dp"
        android:orientation="horizontal">
        <ImageView
            android:id="@+id/callback_dialog_img_state"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:layout_marginLeft="13dp"
            android:layout_marginTop="16dp"
            android:src="@mipmap/ic_success"/>
        <TextView
            android:id="@+id/callback_dialog_tv_title"
            android:layout_width="match_parent"
            android:layout_height="20dp"
            android:layout_marginLeft="7dp"
            android:layout_marginTop="16dp"
            android:gravity="center_vertical"
            android:text="成功"
            android:textColor="#393939"
            android:textSize="14sp"
            android:textStyle="bold"/>
    </LinearLayout>

    <TextView
        android:id="@+id/callback_dialog_tv_msg"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:textColor="#393939"
        android:textSize="14sp"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_marginLeft="1dp"
        android:layout_marginRight="1dp"
        android:background="#EDEDEF"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <TextView
            android:id="@+id/callback_dialog_tv_negate"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center"
            android:padding="12dp"
            android:text="取消"
            android:textColor="#9B9DB1"
            android:textSize="15sp"/>
        <TextView
            android:id="@+id/callback_dialog_tv_dividers"
            android:layout_width="1dp"
            android:layout_height="match_parent"
            android:background="#EDEDEF"/>
        <TextView
            android:id="@+id/callback_dialog_tv_positive"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center"
            android:padding="12dp"
            android:text="确定"
            android:textColor="#007AFF"
            android:textSize="15sp"/>
    </LinearLayout>

</LinearLayout>

布局文件中引用的drawable文件white_shape_8:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
    <solid android:color="#FFFFFF"/>
    <!--圆角弧度可自己修改-->
    <corners android:radius="8dp"/>
    <stroke
        android:width="0.5dp"
        android:color="#EDEDEF"/>
</shape>

然后是自定义的custom,其中包含了是否显示标题、内容是什么、底部按钮显示1个还是2个,都可以在其中进行设置


/**
 * 自定义Dialog
 */
public class CustomDialog extends Dialog {
    private String title;
    private String message;
    private View.OnClickListener onNegateClickListener;
    private View.OnClickListener onPositiveClickListener;
    private String state;//0、警告;1、成功;2、失败;
    private int topShow;//0、隐藏1、显示

    public CustomDialog(Context context) {
        super(context);
    }

    /**
     * @param context 上下文
     * @param theme   给dialog设置的主题
     */
    public CustomDialog(Context context, int theme) {
        super(context, theme);
    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.custom_dialog);
        //设置dialog的大小
        WindowManager m = getWindow().getWindowManager();
        Display d = m.getDefaultDisplay();
        WindowManager.LayoutParams p = getWindow().getAttributes();
        p.width = d.getWidth() - 100; //设置dialog的宽度为当前手机屏幕的宽度-100
        getWindow().setAttributes(p);


        LinearLayout llTop = (LinearLayout) findViewById(R.id.callback_dialog_ll_top);
        llTop.setVisibility(topShow);
        ImageView stateImg = (ImageView) findViewById(R.id.callback_dialog_img_state);
        if (!TextUtils.isEmpty(state)) {
            stateImg.setVisibility(View.VISIBLE);
            stateImg.setImageResource(state.equals("0") ? R.mipmap.ic_photo_smile : state.equals("1") ? R.mipmap.ic_success : R.mipmap.ic_fail);
        } else {
            stateImg.setVisibility(View.GONE);
        }
        TextView textTitle = (TextView) findViewById(R.id.callback_dialog_tv_title);
        if (!TextUtils.isEmpty(title)) {
            textTitle.setVisibility(View.VISIBLE);
            textTitle.setText(title);
        } else {
            textTitle.setVisibility(View.GONE);
        }
        TextView textMsg = (TextView) findViewById(R.id.callback_dialog_tv_msg);
        if (!TextUtils.isEmpty(message)) {
            textMsg.setVisibility(View.VISIBLE);
            textMsg.setText(message);
        }
        TextView divider = (TextView) findViewById(R.id.callback_dialog_tv_dividers);
        TextView negate = (TextView) findViewById(R.id.callback_dialog_tv_negate);
        if (onNegateClickListener != null) {
            negate.setVisibility(View.VISIBLE);
            negate.setOnClickListener(onNegateClickListener);
        } else {
            divider.setVisibility(View.GONE);
            negate.setVisibility(View.GONE);
        }
        TextView positive = (TextView) findViewById(R.id.callback_dialog_tv_positive);
        if (onPositiveClickListener != null) {
            positive.setVisibility(View.VISIBLE);
            positive.setOnClickListener(onPositiveClickListener);
        } else {
            divider.setVisibility(View.GONE);
            positive.setVisibility(View.GONE);
        }

    }

    public void setTitle(String title) {
        this.title = title;
    }

    public void setMsg(String message) {
        this.message = message;
    }

    public void setState(String state) {
        this.state = state;
    }

    public void setTopShow(int topShow) {
        this.topShow = topShow;
    }

    /**
     * 确定按钮
     */
    public void setOnPositiveListener(View.OnClickListener onPositiveClickListener) {
        this.onPositiveClickListener = onPositiveClickListener;
    }

    /**
     * 取消按钮
     */
    public void setOnNegateListener(View.OnClickListener onNegateClickListener) {
        this.onNegateClickListener = onNegateClickListener;
    }
}

然后就可以在代码中引用了:

private void showCustomDialog() {
        final CustomDialog customDialog = new CustomDialog(context, R.style.CustomDialog);//设置自定义背景
        customDialog.setState("0");
        customDialog.setTitle("组队提醒");
        customDialog.setMsg("女神请求与您组队去打Boss!");
        customDialog.setOnNegateListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(context, "您拒绝了与女神组队去闯关!!!", Toast.LENGTH_SHORT).show();
                customDialog.dismiss();
            }
        });
        customDialog.setOnPositiveListener(new View.OnClickListener() {
            public void onClick(View v) {
                Toast.makeText(context, "您已同意与女神组队去闯关!!!", Toast.LENGTH_SHORT).show();
                customDialog.dismiss();
            }
        });
        customDialog.show();
}

上面最主要的是引用的主题,需要在styles.xml中设置一个自定义的style:

<!--自定义用于去除背景-->
    <style name="CustomDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">false</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:background">@android:color/transparent</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:backgroundDimEnabled">true</item>
    </style>

OK,大功告成,如果觉得自定义的不够用,还可以自己修改、增加,目测一个项目有这一个也就够了~~~
