android 模拟返回键

//模拟返回键 相关于ADB方式 有时会无效
try {
Runtime runtime = Runtime.getRuntime();
runtime.exec(“input keyevent " + KeyEvent.KEYCODE_BACK);
} catch (IOException e) {
e.printStackTrace();
}
// 作为第三方app ,调用系统设置无效时，参考调用startactivity 将第三方acitivity调上
if (getRunningActivityName(getApplicationContext()).contains(“Settings$”)){
Intent intent = new Intent(getApplicationContext(), SettingActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
return;
}
//获取当前acitivity
public static String getRunningActivityName(Context context) {
ActivityManager activityManager=(ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
//完整类名
String runningActivity=activityManager.getRunningTasks(1).get(0).topActivity.getClassName();
String contextActivity = runningActivity.substring(runningActivity.lastIndexOf(”.")+1);
return contextActivity;
}
