2.颜色selector：Color List-->selector-->/color/xxx.xml
| 1 2 3 4 5 6 | <?xml version= "1.0" encoding= "utf-8" ?> <selector xmlns:android= "http://schemas.android.com/apk/res/android" > <item android:state_pressed= "true" android:color= "@color/yellow" /> <item android:color= "@color/zise" /> </selector> |
3.尺寸（文件大小、控件大小等）dimens:values-->dimens.xml
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | <resources> <!-- Default screen margins, per the Android Design guidelines. --> <dimen name= "activity_horizontal_margin" >16dp</dimen> <dimen name= "activity_vertical_margin" >16dp</dimen> <dimen name= "btn_head_width" >100dp</dimen> <dimen name= "btn_head_high" >100dp</dimen> <dimen name= "edit_width" >200dp</dimen> <dimen name= "edit_high" >60dp</dimen> <dimen name= "edit_width_xhdpi" >60dp</dimen> <dimen name= "edit_high_xhdpi" >160dp</dimen> <dimen name= "textsize" >20dp</dimen> <dimen name= "EditText_layout_marginTop" >80dp</dimen> <dimen name= "textView_layout_marginTop" >26dp</dimen> </resources> |
4.背景图片:Drawable-->selector-->/drawable/xxx.xml
| 1 2 3 4 5 6 | <?xml version= "1.0" encoding= "utf-8" ?> <selector xmlns:android= "http://schemas.android.com/apk/res/android" > <item android:state_pressed= "true" android:drawable= "@drawable/ic_pressed" ></item> <item android:drawable= "@drawable/ic_default" ></item> </selector> |
5.主题相关
| 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 26 27 28 29 | 常用的系统主题： 1 . 没有标题： @android :style/Theme.Black.NoTitleBar 2 . 全屏幕 @android :style/Theme.Black.NoTitleBar.Fullscreen 3 . 透明 @android :style/Theme.Translucent 4 . 桌面壁纸作为背景 @android :style/Theme.Wallpaper 5 . 对话框 @android :style/Theme.Dialog 对Activity的生命周期是否有影响？ 练习：第一个Activity中有两个按钮， 一个弹出对话框主题的Activity， 另一个弹出对话框，测试二者对 第一个Activity生命周期是否有影响。 弹出对话框主题的Activity： 暂停状态，onPause() 弹出对话框 生命周期没有影响 使用场景： 1 . 对话框主题的Activity 例如：在桌面弹出短信内容对话框 对话框后面的Activity是其他App的，这时必须使用对话框主题的 Activity 2 . 对话框 需要使用Activity中的成员变量时 |
6.设置一按钮点击时图片和文字颜色都有高亮效果
| 1 2 3 4 5 6 7 8 9 10 11 12 13 | <TextView android:id= "@+id/home_tv_city" android:layout_width= "wrap_content" android:layout_height= "wrap_content" android:layout_alignParentLeft= "true" android:layout_centerVertical= "true" android:drawableLeft= "@drawable/selector_home_citymore" android:drawablePadding= "4dp" android:gravity= "center" android:paddingRight= "12dp" android:text= "厦门" android:textColor= "@color/selector_home_city" android:textSize= "20sp" /> |
res/drawable/selector_home_citymore.xml代码:
| 1 2 3 4 5 6 | <?xml version= "1.0" encoding= "utf-8" ?> <selector xmlns:android= "http://schemas.android.com/apk/res/android" > <item android:state_pressed= "true" android:drawable= "@drawable/home_morecity_pre" ></item> <item android:drawable= "@drawable/home_morecity_nor" ></item> </selector> |
res/color/selector_home_city.xml代码:
| 1 2 3 4 5 6 | <?xml version= "1.0" encoding= "utf-8" ?> <selector xmlns:android= "http://schemas.android.com/apk/res/android" > <item android:state_pressed= "true" android:color= "@color/cyan" /> <item android:color= "@color/white" /> </selector> |
7.创建一个shape的selector
| 1 2 3 4 5 6 7 8 9 10 11 | <?xml version= "1.0" encoding= "utf-8" ?> <selector xmlns:android= "http://schemas.android.com/apk/res/android" > <item android:state_pressed= "true" ><shape> <solid android:color= "@color/gray_text" /> </shape></item> <item><shape> <solid android:color= "@color/touming" /> </shape></item> </selector> |
8.代码编写selector
范例:
布局xml代码:
| 1 2 3 4 5 6 7 8 | <TextView android:id= "@+id/TextView_title" android:layout_width= "wrap_content" android:layout_height= "wrap_content" android:focusable= "true" android:drawableTop= "@drawable/selector_tabwidget_icon" android:textAlignment= "center" /> |
selector的xml代码:
| 1 2 3 4 5 6 7 8 9 10 11 12 | <?xml version= "1.0" encoding= "utf-8" ?> <selector xmlns:android= "http://schemas.android.com/apk/res/android" > <!-- Non focused states --> <item android:state_focused= "false" android:state_selected= "false" android:state_pressed= "false" android:drawable= "@drawable/contact" /> <item android:state_focused= "false" android:state_selected= "true" android:state_pressed= "false" android:drawable= "@drawable/contact_sel" /> <!-- Focused states --> <item android:state_focused= "true" android:state_selected= "false" android:state_pressed= "false" android:drawable= "@drawable/contact_sel" /> <item android:state_focused= "true" android:state_selected= "true" android:state_pressed= "false" android:drawable= "@drawable/contact_sel" /> <!-- Pressed --> <item android:state_selected= "true" android:state_pressed= "true" android:drawable= "@drawable/contact_sel" /> <item android:state_pressed= "true" android:drawable= "@drawable/contact_sel" /> </selector> |
selector的java代码:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | StateListDrawable drawable = new StateListDrawable(); //Non focused states drawable.addState( new int []{-android.R.attr.state_focused, -android.R.attr.state_selected, -android.R.attr.state_pressed}, getResources().getDrawable(R.drawable.contact)); drawable.addState( new int []{-android.R.attr.state_focused, android.R.attr.state_selected, -android.R.attr.state_pressed}, getResources().getDrawable(R.drawable.contact_sel)); //Focused states drawable.addState( new int []{android.R.attr.state_focused,-android.R.attr.state_selected, -android.R.attr.state_pressed}, getResources().getDrawable(R.drawable.contact_sel)); drawable.addState( new int []{android.R.attr.state_focused,android.R.attr.state_selected, -android.R.attr.state_pressed}, getResources().getDrawable(R.drawable.contact_sel)); //Pressed drawable.addState( new int []{android.R.attr.state_selected, android.R.attr.state_pressed}, getResources().getDrawable(R.drawable.contact_sel)); drawable.addState( new int []{android.R.attr.state_pressed}, getResources().getDrawable(R.drawable.contact_sel)); TextView textView = (TextView) findViewById(R.id.TextView_title); textView.setCompoundDrawablesWithIntrinsicBounds( null , drawable, null , null ); |
