Android状态栏-字体颜色改变

识别MIUI和FLyme系统

目前只看到了小米和魅族公开了各自的实现方法，支持底层Android4.4以上的版本。而Android官方在6.0版本才有了深色状态栏字体API。所以Android4.4以上系统版本可以修改状态栏颜色，但是只有小米的MIUI、魅族的Flyme和Android6.0以上系统可以把状态栏文字和图标换成深色。

我们首先要了解如何识别手机系统。
这篇文章告诉我们如何判断手机系统

整理出判断MIUI，FLyme系统的方法为

public class OSUtils {
    public static final String ROM_MIUI = "MIUI";
    public static final String ROM_FLYME = "FLYME";
    private static final String KEY_VERSION_MIUI = "ro.miui.ui.version.name";

    private static String sName;
    private static String sVersion;

    public static boolean isMiui() {
        return check(ROM_MIUI);
    }

    public static boolean isFlyme() {
        return check(ROM_FLYME);
    }

    public static boolean check(String rom) {
        if (sName != null) {
            return sName.equals(rom);
        }
        if (!TextUtils.isEmpty(sVersion = getProp(KEY_VERSION_MIUI))) {
            sName = ROM_MIUI;
        } else {
            sVersion = Build.DISPLAY;
            if (sVersion.toUpperCase().contains(ROM_FLYME)) {
                sName = ROM_FLYME;
            } else {
                sVersion = Build.UNKNOWN;
                sName = Build.MANUFACTURER.toUpperCase();
            }
        }
        return sName.equals(rom);
    }

    public static String getProp(String name) {
        String line = null;
        BufferedReader input = null;
        try {
            Process p = Runtime.getRuntime().exec("getprop " + name);
            input = new BufferedReader(new InputStreamReader(p.getInputStream()), 1024);
            line = input.readLine();
            input.close();
        } catch (IOException ex) {
            Log.e(TAG, "Unable to read prop " + name, ex);
            return null;
        } finally {
            if (input != null) {
                try {
                    input.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return line;
    }
}

设置状态栏透明

综合上一篇文章，我们知道Android4.4.+ ,API 19 以上可以设置状态栏透明，且 4.4 和 5.0 方式不同

  /**
     * 设置状态栏透明
     */
    private void setTranslucentStatus() {

        // 5.0以上系统状态栏透明
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Window window = getWindow();
            //清除透明状态栏
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            //设置状态栏颜色必须添加
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(Color.TRANSPARENT);//设置透明
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //19
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

我们设置的主题为NoActionBar，除此之外没添加别的元素。
这里我给button添加了颜色，可以看到button顶到了状态栏。

添加状态栏高度

  public int getStatusBarHeight() {
        int statusBarHeight = 0;
        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            statusBarHeight = getResources().getDimensionPixelSize(resourceId);
        }
        return statusBarHeight;
    }

魅族字体设置方式

 public void setFlymeUI(boolean dark) {
        try {
            Window window = getWindow();
            WindowManager.LayoutParams lp = window.getAttributes();
            Field darkFlag = WindowManager.LayoutParams.class.getDeclaredField("MEIZU_FLAG_DARK_STATUS_BAR_ICON");
            Field meizuFlags = WindowManager.LayoutParams.class.getDeclaredField("meizuFlags");
            darkFlag.setAccessible(true);
            meizuFlags.setAccessible(true);
            int bit = darkFlag.getInt(null);
            int value = meizuFlags.getInt(lp);
            if (dark) {
                value |= bit;
            } else {
                value &= ~bit;
            }
            meizuFlags.setInt(lp, value);
            window.setAttributes(lp);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

小米字体设置方式

public void setMiuiUI(boolean dark) {
        try {
            Window window = getWindow();
            Class clazz = getWindow().getClass();
            Class layoutParams = Class.forName("android.view.MiuiWindowManager$LayoutParams");
            Field field = layoutParams.getField("EXTRA_FLAG_STATUS_BAR_DARK_MODE");
            int darkModeFlag = field.getInt(layoutParams);
            Method extraFlagField = clazz.getMethod("setExtraFlags", int.class, int.class);
            if (dark) {    //黑色字体
                extraFlagField.invoke(window, darkModeFlag, darkModeFlag);
            } else {       
                extraFlagField.invoke(window, 0, darkModeFlag);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Android 6.0 以上设置方式

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    getWindow().getDecorView().setSystemUiVisibility(
                            View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                    | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);

                }

实现方式

这里介绍实现方式的一种，通过自定义基类的Activity，让所有要实现的Activity继承它。

我们的基类布局设置的方式为：状态栏+内容实现布局。
因此在实现过程中我们要将子类布局添加到我们的内容实现布局中，还要将状态栏设置为透明。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <View
        android:id="@+id/view_status_bar_place"
        android:layout_width="match_parent"
        android:layout_height="25dp"/>

    <FrameLayout
        android:id="@+id/frame_layout_content_place"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</LinearLayout>

总的实现方法为，下面是全部代码(要耐心看)

import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.LayoutRes;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;

import android.widget.FrameLayout;

import java.lang.reflect.Method;

        ViewGroup.LayoutParams params = mViewStatusBarPlace.getLayoutParams();
        params.height = getStatusBarHeight();
        mViewStatusBarPlace.setLayoutParams(params);
    }

//将子类布局添加到FrameLayout中
    @Override
    public void setContentView(@LayoutRes int layoutResID) {
        View contentView = LayoutInflater.from(this).inflate(layoutResID, null);
        mFrameLayoutContent.addView(contentView);
    }

        }
        return statusBarHeight;
    }
}

状态栏默认为主题颜色。可以根据需要设置状态栏的颜色，字体是否显示为黑色。
实现代码为：

public class MainActivity extends CompactActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setImmersiveStatusBar(true);
        }
        }
