Android开发App状态栏隐藏和显示及颜色控制处理

在我们开发android app时会经常会遇到控制设备状态栏两种情况，

第一种情况是状态栏的隐藏，例如在首次 引导或闪屏广告时我们不希望显示，希望引导页和闪屏广告布

满整屏来显示，这里只给出关键代码如:

AndroidManifest.xml

public class SplashActivity extends Activity {

其中FullScreen在styles.xml定义如下:

SplashActivity.java

@Override
    protected void onResume() {
        super.onResume();
        isOnBack=true;

        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                if (preferences.getBoolean("firststart", true)) {
                    editor = preferences.edit();
                    //将登录标志位设置为false，下次登录时不在显示首次登录界面
                    editor.putBoolean("firststart", false);
                    editor.commit();
                    if(isOnBack){
                        Intent intent = new Intent();
                        intent.setClass(SplashActivity.this, GuideViewActivity.class);
                        SplashActivity.this.startActivity(intent);
                        SplashActivity.this.finish();
                    }

                } else {
                    if(isOnBack){
                        Intent intent = new Intent();
                        intent.setClass(SplashActivity.this, MainActivity.class);
                        SplashActivity.this.startActivity(intent);
                        SplashActivity.this.finish();
                    }
                }
            }
        }, SPLASH_DISPLAY_LENGHT);
    }

第二种情况是状态栏的显示并控制颜色，只要我们在统一的BaseActivity填加以下代码即可:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //状态栏颜色修改
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            setTranslucentStatus(true);
            SystemBarTintManager tintManager = new SystemBarTintManager(this);
            tintManager.setStatusBarTintEnabled(true);
            tintManager.setStatusBarTintResource(R.color.all_title_bgcolor);//通知栏所需颜色
        }
    }

@TargetApi(19)
    private void setTranslucentStatus(boolean on) {
        Window win = getWindow();
        WindowManager.LayoutParams winParams = win.getAttributes();
        final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
        if (on) {
            winParams.flags |= bits;
        } else {
            winParams.flags &= ~bits;
        }
        win.setAttributes(winParams);
    }
