  • [Android界面] 如何 去掉dialog的黑色背景和边框 DEMO

    android系统的默认对话框是黑色背景,白色边框的样式,对于android系统来说是相当漂亮的,可是与自己的项目风格不搭,所以只好想办法重写他的样式了,当然dialog是支持样式重写的

    使用new Dialog(context, style).setContentView(layout);

    即可定制属于自己项目的dialog

    当然,这儿的style起到了至关重要的作用,要知道那个与项目不搭的白边得全靠它了

    在value下新建style.xml




    下面分享一下我的代码:

    首先:MainActivity

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    14
    15
    16
    17
    18
    19
    20
    21
    22
    23
    24
    25
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
        
       public void dialogStyle(View v){
          final Dialog d=new Dialog(this, R.style.dialog);
           View vv = LayoutInflater.from(this).inflate(R.layout.dialog_test, null);
           TextView delete = (TextView) vv.findViewById(R.id.delete);
            
           d.setCanceledOnTouchOutside(true);
           d.setContentView(vv);
           d.show();
            
           delete.setOnClickListener(new OnClickListener() {
             
            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                d.dismiss();
            }
        });
       }
    }


    然后:style

    1
    2
    3
    4
    5
    6
    7
    8
    9
       <style name="dialog" 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">@null</item> 
    <item name="android:backgroundDimEnabled">false</item> 
    <item name="android:windowBackground"> @android:color/transparent </item>
    </style>


    最后xml

    1
    2
    3
    4
    5
    6
    7
    8
    9
    <!--?xml version="1.0" encoding="utf-8"?-->
    <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">
         
         
        <relativelayout android:layout_width="fill_parent" android:layout_height="wrap_content">
         
        <textview android:id="@+id/delete" android:layout_width="238dp" android:layout_height="58dp" android:background="#2c2c2c" android:text="删除联系人" android:textcolor="#ffffff" android:gravity="center" android:layout_centerhorizontal="true">
    </textview></relativelayout>
    </linearlayout>
