        android:layout_height="fill_parent"
        android:layout_margin="10dip"
        android:orientation="vertical" >

        <TextView

            android:gravity="center"
            android:textColor="#000000"
            android:text="@string/username"
            />

        <EditText

        <TextView
            android:id="@+id/lbl_password"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="15dip"
            android:gravity="center"
             android:textColor="#000000"
            android:text="@string/password"
            />

        <EditText

            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dip"
            android:hint="@string/enter_password"
            android:inputType="textPassword"
            android:singleLine="true" />
         <TextView
            android:id="@+id/lbl_forgot"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="25dip"
            android:gravity="center"
            android:textColor="#000000"
            android:text="@string/forgot_password"
            android:textSize="18dp"
            />

        <Button
            android:id="@+id/loginButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginTop="15dip"
            android:text="@string/login"
             />
    </LinearLayout>

</LinearLayout>

Answer 1

用這個

創建一個新的xml文件，其中包含textfields，edittexts，button，即您要在彈出窗口中顯示的登錄表單。現在，您可以調用以下方法來顯示彈出窗口。

private void callLoginDialog() 
     {
         myDialog = new Dialog(this);
         myDialog.setContentView(R.layout.yourxmlfileID);
         myDialog.setCancelable(false);
         Button login = (Button) myDialog.findViewById(R.id.yourloginbtnID);

          emailaddr = (EditText) myDialog.findViewById(R.id.youremailID);
          password = (EditText) myDialog.findViewById(R.id.yourpasswordID);
          myDialog.show();

         login.setOnClickListener(new OnClickListener()
         {

            @Override
            public void onClick(View v)
            {
                    //your login calculation goes here
            }
        });


     }

Answer 2

將@android:style/Theme.Dialog應用於您的登錄活動。 您可以在Manifest編輯器中執行此操作。

Answer 3

在你的清單文件中給出這樣的

<activity android:name=".LoginActivity"
              android:label="Login"
              android:theme="@style/CustomDialogTheme"
              android:configChanges="locale|keyboardHidden|orientation"/>

並在styles.xml中將customDialogTheme命名為

   <style name="CustomDialogTheme" parent="@android:style/Theme.Dialog">
    <item name="android:bottomBright">#fff</item>
    <item name="android:bottomDark">#fff</item>
    <item name="android:bottomMedium">#fff</item>
    <item name="android:centerBright">#fff</item>
    <item name="android:centerDark">#fff</item>
    <item name="android:centerMedium">#fff</item>
    <item name="android:fullBright">#7D266A</item>
    <item name="android:fullDark">#7D266A</item>
    <item name="android:topBright">#2f6699</item>
    <item name="android:topDark"#2f6699</item>
</style>

使用自定義對話框

為客戶和供應商創建布局

根據您的要求單擊顯示自定義對話框對話框。

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

要么

dialog.setContentView(R.layout.supplierlogin);

dialog.show();
