1.android 改变状态栏的颜色,2 设置透明渐变式的样式!,设置状态栏为透明的渐变的

第一种是设置特定颜色的状态栏,不是渐变透明的在清单文件里面的apilication使用

<applicationandroid:name=".TntApplication"android:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:supportsRtl="true"android:theme="@style/AppTheme">

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"><!-- Customize your theme here. --><item name="colorPrimary">@color/colorPrimaryDark</item><item name="colorPrimaryDark">@color/colorPrimaryDark</item><item name="colorAccent">@color/colorAccent</item><item name="actionMenuTextColor">@color/colorFFFFFF</item><item name="android:windowTranslucentNavigation" tools:ignore="NewApi">false</item>

</style>1.colorPrimary 应用的主要色调，actionBar默认使用该颜色，Toolbar导航栏的底色2.colorPrimaryDark 应用的主要暗色调，statusBarColor默认使用该颜色3.colorAccent  为EditText,CheckBox，RadioButton，SwitchCompat等一般控件的选中效果默认采用该颜色,比如光标4.actionMenuTextColor 菜单栏组件的字体颜色第二种,设置渐变透明的状态栏,底部有虚拟按钮时会自动顶起,getWindow().requestFeature(Window.FEATURE_NO_TITLE);Window window = getWindow();//4.4版本及以上if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);// Translucent navigation barwindow.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);}//5.0版本及以上if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS| WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);window.setStatusBarColor(Color.TRANSPARENT);放在baseActivity就可以了
