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。
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
android:layout_width="match_parent"
android:layout_height="25dp"/>
android:layout_width="match_parent"
android:layout_height="match_parent"/>
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.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;
import java.lang.reflect.Field;
import java.lang.reflect.Method;
/**
* Created by rhm on /1/12.
*/
public class CompactActivity extends AppCompatActivity {
private FrameLayout mFrameLayoutContent;
private View mViewStatusBarPlace;
private final static int MIUI = 0;
private final static int FLYME = 1;
private final static int COMMON = 2;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.activity_status_bar);
mViewStatusBarPlace = findViewById(R.id.view_status_bar_place);
mFrameLayoutContent = (FrameLayout) findViewById(R.id.frame_layout_content_place);
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);
}
/**
* 设置沉浸式状态栏
*
*@param fontIconDark 状态栏字体和图标颜色是否为深色
*/
protected void setImmersiveStatusBar(boolean fontIconDark) {
setTranslucentStatus();
if (fontIconDark) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
setStatusBarFontIconDark(COMMON);
} else if (OSUtils.isMiui()) {
setStatusBarFontIconDark(MIUI);
} else if (OSUtils.isFlyme()) {
setStatusBarFontIconDark(FLYME);
} else {//其他情况下我们将状态栏设置为灰色，就不会看不见字体
setStatusBarPlaceColor(Color.LTGRAY);//灰色
}
}
}
/**
* 设置文字颜色
*/
public void setStatusBarFontIconDark(int type) {
switch (type) {
case MIUI:
setMiuiUI(true);
break;
case COMMON:
setCommonUI();
break;
case FLYME:
setFlymeUI(true);
break;
}
}
public void setCommonUI() {
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);
}
}
public void setFlymeUI(boolean dark) {
try {

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();
}
}
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) { //状态栏亮色且黑色字体
extraFlagField.invoke(window, darkModeFlag, darkModeFlag);
} else {
extraFlagField.invoke(window, 0, darkModeFlag);
}
} catch (Exception e) {
e.printStackTrace();
}
}
public void setStatusBarPlaceColor(int statusColor) {
if (mViewStatusBarPlace != null) {
mViewStatusBarPlace.setBackgroundColor(statusColor);
}
}
/**
* 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);
}
}
//设置状态栏高度
public int getStatusBarHeight() {
int statusBarHeight = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
statusBarHeight = getResources().getDimensionPixelSize(resourceId);
}
return statusBarHeight;
}
}
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);
}
}
下一篇，我会介绍另一种实现方式。
