方式2.透明状态栏效果，需要在5.0及其以上系统才支持。

import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
public class Status2Activity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status2);
if (Build.VERSION.SDK_INT >= 21) {
View decorView = getWindow().getDecorView();
int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
decorView.setSystemUiVisibility(option);
getWindow().setStatusBarColor(Color.TRANSPARENT);
}
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
}
}
方式3.将状态栏和导航栏设置为透明
android:fitsSystemWindows=“true”
- Step2 在Activity文件的setContent()方法之前加入下面代码
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
//透明状态栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//透明导航栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
方式4.将状态栏和导航栏设置为透明
android:fitsSystemWindows=“true”
- Step2 使用SystemBarTintManager和StatusBarUtil对状态栏进行设置
只需一行代码即可设置指定颜色的沉浸式状态栏
/** 设置沉浸式状态栏 */
StatusBarUtil.initSystemBar(this, R.color.white);
下面附上代码
