java - 对话框宽高问题

Question

我使用自定义对话框，但在移动设备和选项卡 View 中，但当我检查选项卡时设计发生了变化

我想在所有设备上使用相同的对话框。

查看我下面的代码。

private void startDialog() {

    final Dialog dialog = new Dialog(activity);
    int width = (int)(getResources().getDisplayMetrics().widthPixels*0.70);
    int height = (int)(getResources().getDisplayMetrics().heightPixels*0.65);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    dialog.setContentView(R.layout.checkout_alert_dialog);
    dialog.show();
    dialog.getWindow().setLayout(width, height);


    btn_cancle = dialog.findViewById(R.id.btn_cancle);
    btn_cancle.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(activity, "Cancel coming soon", Toast.LENGTH_LONG).show();
            dialog.dismiss();
        }
    });

    btn_continue = dialog.findViewById(R.id.btn_continue);
    btn_continue.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(activity, " Ok coming soon", Toast.LENGTH_LONG).show();
            dialog.dismiss();
        }
    });
}

下面是Dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"

只要看看你的 layout.xml 你的布局 height 和 width 是 match_parent 然后它创建一个空格.

只需用我的 xml 替换你的 xml 即可。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="@dimen/_250sdp"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="@color/white"
    >

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

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

            <ImageView
                android:id="@+id/iv_pointBox"
                android:layout_width="@dimen/_80sdp"
                android:layout_height="@dimen/_80sdp"
                android:src="@drawable/ic_chekout_popup"
                android:layout_gravity="center_horizontal"
                android:layout_marginTop="@dimen/_30sdp"
                />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="@dimen/normal_input_text_size"
                android:text="You've chosen to redeem 865 Points and pay 44.44 AED. The Payment process might take Some times, please do not hit the back button or close the app. Would you like to continue. "
                android:layout_centerHorizontal="true"
                android:layout_marginLeft="@dimen/_20sdp"
                android:layout_marginRight="@dimen/_20sdp"
                android:layout_below="@+id/iv_pointBox"
                android:layout_marginTop="@dimen/_15sdp"
                />
         <View
             android:layout_width="match_parent"
             android:layout_height="@dimen/_1sdp"
             android:background="@color/view_color"
             android:layout_marginTop="@dimen/_50sdp"
             />
         <LinearLayout
             android:id="@+id/linerbutton"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:orientation="horizontal"
             >
            <Button
                android:id="@+id/btn_cancle"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:text="@string/lable_cancel"
                android:textColor="@color/black"
                android:textSize="@dimen/normal_input_text_size"
                android:textStyle="bold"
                android:background="@null"
                android:gravity="center"
                android:layout_weight="1"
                />

             <View
                 android:layout_width="@dimen/_1sdp"
                 android:layout_height="@dimen/_45sdp"
                 android:background="@color/view_color"
                 />
            <Button
                android:id="@+id/btn_continue"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:text="@string/lable_continue"
                android:textColor="@color/black"
                android:textSize="@dimen/normal_input_text_size"
                android:textStyle="bold"
                android:background="@null"
                android:layout_weight="1"
                android:gravity="center"
                />
         </LinearLayout>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

并在 java 文件中删除以下三行 无需在运行时更改 height 和 width:

int width = (int)(getResources().getDisplayMetrics().widthPixels*0.70);
 int height = (int)(getResources().getDisplayMetrics().heightPixels*0.65);
 dialog.getWindow().setLayout(width, height);
