Question

我尝试了很多方法，但无法解决此对齐问题。而且我不确定我哪里出错了。

我的XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical"
    android:background="@color/popover">

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Large Text"
            android:textColor="#000000"
            android:layout_marginTop="15dp"
            android:layout_marginBottom="2dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Large Text"
            android:textColor="#000000"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView
            android:id="@+id/textView3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Large Text"
            android:textColor="#000000"
            android:layout_marginTop="2dp"
            android:layout_marginBottom="5dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView
            android:id="@+id/textView4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Medium Text"
            android:textColor="#000000"
            android:paddingLeft="20dp"
            android:paddingRight="20dp"
            android:layout_margin="5dp"
            android:textAppearance="?android:attr/textAppearanceMedium" />

        <TextView
            android:id="@+id/textView5"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Small Text"
            android:textColor="#000000"
            android:layout_margin="5dp"
            android:textAppearance="?android:attr/textAppearanceSmall" />

        <TextView
            android:id="@+id/textView6"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Small Text"
            android:textColor="#000000"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:textAppearance="?android:attr/textAppearanceSmall" />

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:layout_marginTop="15dp"
            android:layout_marginBottom="10dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp" >

            <ImageButton
                android:id="@+id/locationalert_dont"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="5dp"
                android:layout_marginRight="5dp"
                android:background="@drawable/dontallow_btnaction" />

            <ImageButton
                android:id="@+id/locationalert_ok"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginRight="5dp"
                android:background="@drawable/ok_btnaction" />

        </LinearLayout>

    </LinearLayout>

和班级档案：

public void showLocationDialog()
    {

        Dialog dialog = new Dialog(Homescreen.this);
        dialog.setContentView(R.layout.locationalert);

        TextView tv1 = (TextView)dialog.findViewById(R.id.textView1);

        TextView tv2 = (TextView)dialog.findViewById(R.id.textView2);

        TextView tv3 = (TextView)dialog.findViewById(R.id.textView3);

        TextView tv4 = (TextView)dialog.findViewById(R.id.textView4);

        TextView tv5 = (TextView)dialog.findViewById(R.id.textView5);

        TextView tv6 = (TextView)dialog.findViewById(R.id.textView6);

        ImageButton ok = (ImageButton)dialog.findViewById(R.id.locationalert_ok);

        ImageButton dont = (ImageButton)dialog.findViewById(R.id.locationalert_dont);

        dialog.show();

    }

实际上我在课堂上有一个按钮，然后点击它弹出这个对话框。但对话框显示为

enter image description here

在截图中，我得到一个标题黑条以及弹出对话框，我不知道如何删除它。

任何相关的答案都是可取的。提前致谢。

Answer 1

尝试以下代码： -

final Dialog dialog = new Dialog(ActivityName.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); // hide title bar
dialog.setContentView(R.layout.vip_services_other_dialog);

// hide black background
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

Answer 2

使用

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

请同时通过：

Android Window and Related Flags和Dialogs

Answer 3

在XML（locationalert）中，将“线性布局背景”设置为：

android:background="@android:color/transparent"

并在showLocationDialog（）方法中添加

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(R.color.YOURCOLOR));

Answer 4

这是您的问题的解决方案

 Dialog dialog = new Dialog(Homescreen.this,android.R.style.Theme_Translucent_NoTitleBar );
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.locationalert);

Answer 5

您可以隐藏标题栏和对话框的背景，如下所示：

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

希望这会有所帮助.. :)
