1：修改frameworks/base/packages/SystemUI/src/com/Android/systemui/SystemUIService.Java

import android.content.IntentFilter;

[java] view plain copy

@Override
public void onCreate() {
// Pick status bar or system bar.
IWindowManager wm = IWindowManager.Stub.asInterface(
ServiceManager.getService(Context.WINDOW_SERVICE));
try {
SERVICES[0] = wm.canStatusBarHide()
? R.string.config_statusBarComponent
: R.string.config_systemBarComponent;
} catch (RemoteException e) {
Slog.w(TAG, "Failing checking whether status bar can hide", e);
}
final int N = SERVICES.length;
mServices = new SystemUI[N];
for (int i=0; i<N; i++) {
Class cl = chooseClass(SERVICES[i]);
Slog.d(TAG, "loading: " + cl);
try {
mServices[i] = (SystemUI)cl.newInstance();
} catch (IllegalAccessException ex) {
throw new RuntimeException(ex);
} catch (InstantiationException ex) {
throw new RuntimeException(ex);
}
mServices[i].mContext = this;
Slog.d(TAG, "running: " + mServices[i]);
mServices[i].start();
}
//add by xiaoge
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_DISPLAY_STATUS_BAR);
intentFilter.addAction(Intent.ACTION_HIDE_STATUS_BAR);
registerReceiver(mStatusBarReceiver, intentFilter);
}
//add by xiaoge
BroadcastReceiver mStatusBarReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent != null) {
String action = intent.getAction();
final int N = SERVICES.length;
for (int i = 0; i < N; i++) {
Slog.d(TAG, "invoke: " + mServices[i] + "'s onReceive()");
mServices[i].onReceive(action);
}
}
}
};

2：修改frameworks/base/core/java/android/content/Intent.java

[java] view plain copy

//add by xiaoge
@SdkConstant(SdkConstantType.BROADCAST_INTENT_ACTION)
public static final String ACTION_DISPLAY_STATUS_BAR = "android.intent.action.DISPLAY_STATUS_BAR";
@SdkConstant(SdkConstantType.BROADCAST_INTENT_ACTION)
public static final String ACTION_HIDE_STATUS_BAR = "android.intent.action.HIDE_STATUS_BAR";
//add ends

3：修改frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/StatusBar.java

[java] view plain copy

4：修改frameworks/base/packages/SystemUI/src/com/android/systemui/SystemUI.java

[java] view plain copy

package com.android.systemui;
import java.io.FileDescriptor;
import java.io.PrintWriter;
import android.content.Context;
import android.content.res.Configuration;
public abstract class SystemUI {
public Context mContext;
public abstract void start();
public abstract void onReceive(String action);//add by xiaoge
protected void onConfigurationChanged(Configuration newConfig) {
}
public void dump(FileDescriptor fd, PrintWriter pw, String[] args) {
}
}

5：修改frameworks/base/packages/SystemUI/src/com/android/systemui/power/PowerUI.java，添加函数

[java] view plain copy

//add by xiaoge
public void onReceive(String action) {
}

6：显示statusbar方法：sendBroadcast(new Intent(Intent.ACTION_DISPLAY_STATUS_BAR));

或者sendBroadcast(new Intent("android.intent.action.DISPLAY_STATUS_BAR"));

7：隐藏statusbar：sendBroadcast(new Intent(Intent.ACTION_HIDE_STATUS_BAR));

或者sendBroadcast(new Intent("android.intent.action.HIDE_STATUS_BAR"));

android 隐藏statusbar
