3 个解决方案

#1

For question 2 add

对于问题2添加

requestWindowFeature(Window.FEATURE_NO_TITLE);

Right before :

就在之前：

setContentView(R.layout.activity_first);

#2

To Full Screen use,

要全屏使用，

super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.my_layout);

FOR OVERFLOW MENU, please elaborate more What u want..?

对于OVERFLOW MENU，请详细说明你想要什么..？

#3

for your Question 2: in onCreate()

对于你的问题2：in onCreate（）

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

this is to make action bar icon transparent

这是为了使动作栏图标透明

getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));

in Manifest.xml

在Manifest.xml中

<android:theme="@android:style/Theme.NoTitleBar">
