1. 去掉标题栏+全屏显示+导航栏半透明
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// todo 去掉标题栏
supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
// todo 全屏显示以及导航栏半透明
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
@Override
protected void onDestroy() {
super.onDestroy();
// todo 还原设置
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
}
2. 去掉标题栏+全屏显示+设置导航栏颜色
public class MainActivity extends AppCompatActivity {
private int mNavigationBarColor;
@Override
protected void onCreate(Bundle savedInstanceState) {
// todo 去掉标题栏
supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
// todo 全屏显示
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
// todo 设置导航栏颜色
mNavigationBarColor = getWindow().getNavigationBarColor();
getWindow().setNavigationBarColor(Color.TRANSPARENT);
}
@Override
protected void onDestroy() {
super.onDestroy();
// todo 还原设置
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setNavigationBarColor(mNavigationBarColor);
}
}
3. 对DecorView进行设置
public class MainActivity extends AppCompatActivity {
private int mSystemUiVisibility;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View decorView = getWindow().getDecorView();
// todo 获取当前的ui状态
mSystemUiVisibility = decorView.getSystemUiVisibility();
// todo 全屏
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
}
@Override
protected void onDestroy() {
super.onDestroy();
// todo 还原ui状态
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(mSystemUiVisibility);
}
}
4. 清单文件设置主题
- 在/res/values/styles.xml中自定义全屏主题
<style name="FullScreen" parent="Theme.AppCompat.Light.NoActionBar">
<!--窗口全屏-->
<item name="android:windowFullscreen">true</item>
<!--导航栏半透明-->
<item name="android:windowTranslucentNavigation">true</item>
</style>
- 在清单文件中设置主题
<activity
android:name=".MainActivity"
android:theme="@style/FullScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
